When turning on the PC, Windows 10 users may encounter a blue screen of death and a message that "The computer has not started correctly" and it is recommended to restart it. This error indicates that the system files are damaged, and that changes have been made in the registry editor.

A similar error with the message "It seems that the Windows system did not boot correctly" may occur when the PC is turned off, during the installation of the antivirus, and the removal of software. There are several methods to fix these errors.

Ways to solve the problem

If you encounter an error when the computer does not start correctly, you should double-check the settings for automatically creating restore points for Windows 10 and use one of the check dates. To do this, boot from the system recovery environment, select "Troubleshooting" or "Diagnostics" (if you boot into safe mode).

The System Restore Wizard will start. We select the checkpoint before the appearance of the blue screen of death and press "Next".

After restoring the system, Windows 10 will boot as usual. If this method did not help to solve the problem, proceed to the next method.

IMPORTANT! This method can make the problem worse. Therefore, if you cannot solve the problem and are ready for drastic methods, up to reinstalling the system, you should use the following recommendations.

In the additional parameters, select "Command line".

We enter the following commands in order:

A list of sections will appear. It is worth remembering the letter of the system partition and the one reserved by the system.

We run the integrity check system files, entered the command "sfc / scannow / offbootdir = C: \ / offwindir = E: \ Windows", where E is the Windows 10 drive and C is the Windows 10 boot loader.

In the case when the system issues a refusal and notifies that resource protection cannot perform this operation, simply enter the following commands:

• E: - press "Enter" (E is a disk with Windows 10);
• md configbackup;
• cd Windows \ System32 \ config \;
• copy * e: \ configbackup \;
• cd Windows \ System32 \ config \ regback \;
• copy * e: \ windows \ system32 \ config \ - for a request to replace files, press the English "A" and click "Enter". With this operation, we start the restoration of the registry.

After executing the command, close all windows. You need to restart your computer. Windows 10 should boot as usual.

If the problem persists and the computer does not boot correctly, all actions performed in the command line can be canceled by entering the following tasks:

• cd e: \ configbackup \
• copy * e: \ windows \ system32 \ config \

Also, the computer should be checked for viruses that can make changes to the registry. If no malicious objects were found, the automatic repair failed and the Windows 10 computer continues to boot incorrectly, developers Microsoft recommend performing a clean install of the system from under the BIOS. In this case, Windows 10 will start correctly.

Windows 10: recovery, options, instructions and recommendations. How to repair Windows 10 bootloader

The initial version of the tenth, "beloved and adored" Windows OS in the form of a free preliminary release of the Technical Preview was not at all what was expected of it. It was only later that modifications like Pro, Home, Education, Enterprise and Ultimate came out. But all of them, as well as the previous "operating systems", tend to "fly off" at the most inopportune moment. Now the question will be considered related to how the Windows 10 system is restored in the most elementary ways. This, I think, will not cause any difficulties for anyone.

Windows 10: recovery. What you should pay attention to?

Note, the "ten", no matter how perfect it may seem, has absolute identity with its predecessors. This is not so much connected with viruses or malicious codes, how much with errors of the system itself.

First of all, you need to pay attention to installed version... If this was the initial Technical Preview OS, intended for review and installation on top of an existing "OS", it is not so difficult to rollback. By the way, it should be said separately that to restore working capacity new system provided that the old files are not deleted, it is very simple.

Immediately, we note that there will be two Windows folders... The first (main) is responsible for the safety of the previous one. The second is the installation directory for the new OS. Unfortunately, not every user will be able to determine which Windows 10 restore point he needs, let alone find a backup copy on the disk, not to mention the file itself responsible for this process.

Windows 10 Standard Post-Installation Recovery Procedure

System rollback, as a rule, can be used in two cases: either recovering "tens" after critical failures, or returning to operating system on top of which it was installed. Here you need to understand the difference.

In the first option, everything is, in general, simple. The standard Windows Restore service will be enabled in any case. When installed, for example, "ten" on top of the "seven", it is the service of the new system that has priority.

But with the return to the old OS and its settings, the situation is somewhat more complicated. The fact is that the standard Windows 10 restore point is not the key point in this case. Here, the primary role is played by the image of the previous system, which takes up a lot of space on the hard drive.

Removing it even when using the standard system disk or partition cleaning tool, when all unnecessary components are ticked off, you can only achieve that the previous "operating system" will not be restored, by and large, it will not even be reinstalled without selecting another partition or formatting the existing one ... In addition, you immediately need to pay attention to the fact that restoring the Windows 10 system makes sense without rolling back to the previous one. But the "ten" itself, which is, so to speak, on priority rights, blocks any other previously installed OS. The only exception is the bootloader, where you can select the correct component to start.

Preliminary steps for uninstalling updates

Another important aspect is the installation of updates. In Windows 10, recovery can be associated, oddly enough, with this. The fact is that updates, starting with the "seven", came out rather inoperative. Ultimately, updates are not only installed incorrectly, they generally cause critical failures in the system itself.

To remove packages, you need to use a standard function called from the "Control Panel". Here you need to take into account the installation date of each update. For sorting it is worth choosing change or installation by date. Service packs are usually referred to as KB. True, most of them are related, rather, to the installation of additional components of the Windows security system.

To cancel their installation, you just need to use the uninstall line of each update, after which the computer is completely rebooted. In the best case, the Windows 10 recovery disk will help. But these steps are applicable in the case of OS recovery, so to speak, to the factory state. In addition, you will have to turn off each of them and see how it affects the system as a whole.

Windows 10 automatic recovery

Concerning automatic recovery, any currently created OS reserves space on the hard drive, creating its own partition, different from the system one, used to save the parameters and settings of the "operating system" installed at the moment.

On the other hand, if the system crashed, you should first restart it. In some cases (especially when "Windows" hangs), you have to reboot in forced mode, for example, on laptops, this is done by pressing and holding the power button.

After that, a new boot of the system will occur and a message about the possibility of recovery will appear. But this is more true for systems like XP, 7 and 8. There is nothing like this in the top ten. In Windows 10, recovery is slightly different. The system does not offer a choice, it recovers files on its own. But this only works under the condition of non-critical failures. When download files get corrupted, you have to think.

Bootloader problems

Now let's move on to the most big problems systems. Recovery Windows boot 10 after failures is impossible without understanding the process itself, which applies equally to all systems in this series.

The boot sector is the fastest in terms of access area of ​​the hard drive, which contains information about the system files required to boot the OS. In this section, there is a kind of table that provides indexing of the contents of one or another file used in the process of loading the operating system. If failures were found in it, the system will have to be reinstalled.

Restoring the operating system boot

The simplest method for restoring the Windows 10 bootloader is considered to be the option that is applicable to all systems of this type. This type may not work if booting from a hard disk or damaged partition. Usually, a Windows 10 recovery disk is used to restore the operating system. This avoids many problems and has the function of calling and controlling the so-called console.

This is the Bootrec.exe / FixMbr command entered in the command line (mind you, not through the Run menu, but through the cmd line entered in the same place). Recovery of the Windows 10 bootloader is carried out according to the same principles that were laid down in version 7 and higher. Some commands may not work.

Sequentially, after the first line, the Bootrec.exe / FixBoot command is added (again, provided that it is booted from disk). Further, if Windows 10 boot recovery is not possible in this way, you will need to check the presence of all operating systems present on this device... This is done simply. But for this, in the same console, you will need to use the Bootrec.exe / ScanOs command. Further, if nothing helped at all, the recovery of the Windows 10 bootloader can be continued except with the command of a complete overwrite of sectors and recovery initial parameters... This is the Bootrec.exe / ReBuildBcd command.

Create a boot disk

For many users, the most simple solution is the disk. Windows 10 system recovery is carried out automatically, but only when the mode of reading data and booting from the corresponding device via BIOS is enabled (detection of the HDD boot device must be disabled, and removable CD / DVD media is installed as the first device).

Then the disk image itself is created. To do this, you can use utilities like UltraISO or a standard system tool (of course, if you have the original Windows 10 distribution).

Saving copies of disk images and partitions

Often, file recovery is also required. Windows 10, like any other "operating system" of this family, can create images of hard drives and logical partitions with user data stored in them.

But for this it is better to use not standard means, and specialized utilities like Acronis True Image. With the help of such programs, an image of a system, hard disk or logical partition is created in a couple of clicks, and with the help of them it is possible to subsequently restore all the necessary information.

Recovery from image

As for the process itself, Windows 10 recovery allows you to either automatic mode, or on demand.

For the process on demand, you should use the archiving and update section, which is located in the standard "Control Panel". In it, you need to go to advanced recovery methods, and then use a previously created copy of the system image indicating the location of the file.

Which is better to use?

You can do it even easier. In Windows 10, data recovery can be done using third party utilities like the aforementioned Acronis True Image program.

Actually, the process itself is very similar to the standard one, but it is more optimized for an ordinary user who does not want to go into the jungle of system settings.

As for recovering accidentally deleted files, specialized software like the Recuva program or the very powerful R.Saver package will come in handy, which allow you to find data on any media and restore it to its initial state, while preserving the desired location and even metadata. But this, as they say, is a separate topic.

What do we end up with?

On the whole, as can be seen from the above material, restoring the "dozens", as well as older versions of Windows OS, is not difficult. The main thing is to be patient, since some processes can be quite lengthy in time. On the other hand, if you do recovery, it's still better than reinstalling Windows 10 again, especially since after reinstallation, user files, folders and programs may be lost.

As for the recovery method or the preferred program to be used, here each user must decide for himself. It is clear that not only recovery discs can be created. A bootable flash drive can be used with equal success. True, in this case, you will have to pay special attention to BIOS settings to set the USB device as the boot source. And this is done with a flash drive already inserted into the port even before the computer or laptop is turned on, otherwise the BIOS simply will not detect it. So be careful.

"The computer did not start correctly" error in Windows 10

Sometimes it may happen that when starting the tenth Windows versions on the "Automatic Repair" screen, a notification appears that the computer has not started correctly or that the operating system has not loaded correctly. To fix this problem, you need to know the cause so that you can choose the right solution.

Initially, it is worth noting that if the error pops up after turning off the PC or stopping the update of the "dozen", but it is eliminated by a simple restart of the computer, and then it occurs again, or when the PC does not immediately turn off, after which it is restored in automatic mode, then this instruction won't come in handy. In this case, this can be influenced by several reasons.

The most common reason for this behavior of the computer is power problems, perhaps even the power supply is junk. In this case, after several attempts to start the operating system in automatic mode, the recovery of the operating system is activated. The second most popular option is problems with disconnecting the PC and the fastboot mode. It is worth deactivating here quick start.

It can also be caused by driver problems. For example, on laptops with Intel processors downgrading the Intel Management Engine Interface driver to a previous version may well fix this disconnect issue. In addition, you can run a scan and restore the integrity of data "tens".

If the problem occurs after a system reset or update The most common occurrence of a notification that the PC is not loaded correctly looks something like this. After resetting the operating system, the blue screen with the INACCESSIBLE_BOOT_DEVICE notification, however, this may indicate more serious problems. In this case, everything is much simpler. After that, the data is reset, as a result of which the "Restore" window appears with the "Additional parameters" button and a reboot is performed. This method can be used in other variants of the manifestation of a similar error. This is a completely safe way.

In this window, you need to go to "Advanced options", where you need to click "Troubleshooting". On this screen, you need to click on the "Advanced options" again, in which the "Boot options" are located. You need to click on them, and then click "Restart".

In the "Boot Options" you need to press F6 to start Safe Mode with the ability to work with the command line. If this succeeds, then you need to log in as an administrator.

In the command line that appears, several entries must be made in a certain sequence. When you enter the first, error notifications may pop up or they will take a long time to complete. In that case, you just need to wait.

Initially, you must enter sfc / scannow. Then you should write dism / Online / Cleanup-Image / RestoreHealth. The last command shutdown –r will restart the computer. You must wait until the computer boots up. Basically, such actions are able to correct the error and return the normal startup of the operating system.

"The computer did not start correctly" or "It seems that the system did not boot correctly" If after starting the PC or laptop, a notification appears informing that the computer is being checked, and behind it a blue screen appears with the notification that the PC is not started correctly and a proposal to restart it or visit additional settings , this may indicate defects in some system files of the operating system.

Such a problem may arise after turning off the power during an update, installing an antivirus or removing viruses from a PC, cleaning the registry, as well as installing unknown programs.

You can still solve this problem. If a situation has occurred in which the automatic creation of recovery marks is activated in the system, then you should try to use this feature. This can be done quite simply.

It is required to click "Advanced options", and in the window that appears, select "Troubleshooting". Then again you need to click "Advanced options", where you should find "System Restore".

In the window that appears, click "Next" and, if a suitable rollback mark is found, it must be applied. Most likely, these actions will be able to get rid of the error. If there are no marks, then you need to click "Cancel". After fixing the problem in another way, it is imperative to activate the automatic creation of rollback marks.

By pressing the "Cancel" button, a blue screen will appear. On it you need to click on "Troubleshooting".

After that, you can take the next steps that can lead to the return of the launch. In this case, the command line will be applied. It is necessary to click on the button "Reset the PC to its original state", which will reset the system, but the ability to save personal data will remain, and all programs will be deleted. If there is a desire to return to its original state, then you need to click "Additional parameters", and then select "Command line".

It is worth noting that using this method you can seriously harm your computer, so you need to tackle it only with complete confidence in your actions.

Using command lines, it will sequentially check the integrity of files and system elements, repair them and restore the registry from a backup copy. Basically, these steps will help fix the problem.

The first step is to introduce diskpart. Then you need to write list volume. After that, a list of disk volumes should appear. Here you need to find out and remember the letter of the system partition with the operating system. In addition, you must remember the "System Reserved" volume letter. After that, you need to enter exit.

Next, write sfc / scannow / offbootdir = C: \ / offwindir = E: \ Windows to scan for data integrity. Here C: is a drive with a bootloader, and E: is a disk with an operating system. In this case, a notification may pop up stating that this procedure cannot be performed. Here you need to continue executing commands. Then you should write E :. After that, you need to write md configbackup, then cd Windows \ System32 \ config \. Next, you need to run copy * e: \ configbackup \.

The next command will be cd Windows \ System32 \ config \ regback \. Then you need to enter copy * e: \ windows \ system32 \ config \, after which a request will pop up to replace the files. Here you need to press A in the Latin layout and then Enter. These actions will start restoring the registry from a backup that is automatically created by the operating system.

After that, you need to exit the command line and in the Select Action window, click Continue. Exit and Windows application 10".

After that, the system should start. If this does not happen, then using the command line, you can undo all adjustments. To do this, you must sequentially enter cd e: \ configbackup \, and then copy * e: \ windows \ system32 \ config \, then press A and Enter. If none of this helped, then all that remains is to reset Windows 10 to factory settings.

The computer is not started correctly: what to do?

All Windows operating systems, including the most stable seventh or the newest tenth version, are characterized by the appearance of failures when the system does not boot in normal mode and informs the user that the computer has not started correctly. What is the reason and how to deal with it, see below.

The computer did not start correctly (Windows 8.1, 8, 10): the main causes of failures

As for the reasons causing this behavior of the system, there can be a lot of them. According to statistics, most often such failures occur due to improper shutdown of the computer, forced stopping of some processes (for example, updates), damage to system files or even the bootloader itself.

The most common are failures with error descriptions like INACCESSIBLE_BOOT_DEVICE (not available boot device), CRITICAL_PROCESS_DIED (interrupted critical process) or something like that.

Very often, notifications that the computer is not started correctly and because of this Windows cannot start in normal mode can be found in case of voltage drops, when the terminal spontaneously disconnects from the network when there is no uninterruptible power supply or stabilizer, when the power supply overheats, etc. .d. We should also pay special attention to the functionality of all "iron" components. But these are trifles. Situations look much worse when the system contains viruses that violate Windows work, or for some reason the components responsible for loading the system fail. Let's consider a few common cases of such problems and the main methods of eliminating them, without touching on problems with the "hardware".

What's the first thing to do?

So, if suddenly a situation occurs when the computer is not started correctly and the system cannot start, it may very well be that this is a fleeting failure. In this case, first you need to reboot the system or just turn off the terminal in the usual programmatic way from the "Start" menu.

If this is not possible, you will have to apply a forced shutdown by long pressing the power button on system unit or on the laptop panel.

As a rule, after such a procedure, at startup, the system initiates a check of the system disk for errors, after which it can boot in normal mode. The visual check can be observed in Windows 7 and below. In later versions, it is done in the background.

Virus check

Equally important if a message appears that the computer has not started correctly is system diagnostics for the presence of virus threats. If the system does not start at all, it is quite problematic to do this.

Therefore, it is recommended to use special utilities like Kaspersky Rescue Disk, from which the boot is performed even before Windows starts. In the utility itself, to facilitate the task, you can use its own graphical interface, and it works much better than stationary scanners, allowing you to identify many threats even in random access memory or boot sectors.

Automatic recovery. The computer did not start correctly (Windows 10 and below)

In general, almost all recent Windows systems are characterized by the presence of a special self-recovery module after critical failures. This is the so-called automatic recovery. The computer did not start correctly, the system does not boot, although there are signs of operability. In this situation, System Restore should start automatically.

A corresponding notification about the start of the analysis for system recovery appears on the screen. But this only works if Windows has a fixed rollback point. If the user cleaned or deleted previously created restore points before the crash, nothing will work. The backup simply does not have a copy from which to roll back to the previous state.

In the seventh version of the operating system and below, fixing this situation looks much easier. When starting the system at the boot stage, you should use the F8 key, which is used to select the safe boot mode, but in the menu that appears, you need to select the boot of the last working configuration (again, if possible). By the way, in the tenth version it is also possible to configure the use of the F8 key to call such a menu.

Boot in safe mode with checking the integrity of system files

The situation is somewhat more complicated with the damage of the system components of the system with the impossibility of their restoration in automatic mode (at startup or reboot after the notification that the computer has not started correctly). What to do in this case?

To begin with, you can try to boot into safe mode, and then use command line invoked from the Run console (Win + R). If for some reason this boot option is not possible, you should set safe mode with confirmation on the command line to determine the component where the boot stops. In this situation, the command line will have to be invoked from the Recovery Console from the installation disc.

In both cases, sfc / scannow is written on the command line, after which the system will automatically check and restore the failed components. But this does not always help.

Disable driver signature verification

Now let's look at the situation when the computer does not start correctly (Windows 10 on board). In the tenth version, getting to the safe mode is quite problematic. Here you will need an installation or recovery disk, when booting from which, in the recovery section, you need to select additional settings and go to diagnostics, and then use the boot options menu.

In the menu that appears, there is a line for disabling verification digital signature drivers, standing under the seventh number. You need to move to it and press the enter key (you can do this faster by pressing the number 7 on the keyboard).

This problem is very often associated with the oem-drc64.sys driver. If disabling signature verification worked, you need to enter the registry editor in the system (regedit in the Run menu) and go down the HKLM branch through the SYSTEM section to the CurrentControlSet directory, which contains the Services directory. Find the driver folder here and delete it.

Restoring the system from an image

It is believed that the best option for restoring the system to work after a message appears stating that the computer has not started correctly (Windows 10 is in use or any other version) is to restore from a previously captured system image.

Not everyone, however, thinks about such things in advance, nevertheless, the very process of putting Windows in order in this case turns out to be the fastest and simplest.

Using the command line with an incomplete or aborted update

There are also situations when problems with the fact that the computer did not start correctly (8.1, 8, 7 or 10 modifications on board) are associated with an incomplete or interrupted system update. You can also fight these failures.

We call the command line at boot, as shown earlier, and write the command shown below there:

Hard recovery commands

If this option does not help, the computer is not started correctly and the system does not boot, you can try to do an authoritative recovery.

To do this, first write three commands on the command line:

• diskpart;
• list volume;
• exit.

Be sure to remember the letter of the system partition, since in most cases it will differ from the generally accepted value "c" (most often the system partition "e" will appear).

After entering each command, the enter key is pressed. In theory, this method gives an almost 100% guarantee of Windows recovery.

Boot Loader Repair

Finally, if the computer does not start correctly, Windows of all versions offers another universal solution that allows you to restore the bootloader, which may be damaged.

To do this, in the same command console, you must first use the chkdsk check command c: / f / r, and then directly the restore directives, as shown below:

Then you can reboot. The system, if the failure was associated with the bootloader, will work like a clock.

If all else fails

Finally, about one more situation when none of the above does not help. We'll have to deal with reinstalling Windows. But in order not to "demolish" the entire system, when booting from the installation disk in the diagnostics section, you need to select the item to return the computer to the so-called initial state.

This approach provides for the option of saving user files, after which it will be possible to perform a "clean" installation of Windows, which in most cases allows you to get rid of software failures much better than all the checks combined. But this, as already clear, should be done only in the most extreme case, when all other means were powerless.

Instead of a total

Finally, it remains to add that the situation when the computer is not started correctly or the system does not start can be connected precisely with the "hardware". In particular, problems with the graphics chip or hard disk when it starts to "crumble". If these are really physical problems, there is nothing to be done. But for the correct determination of malfunctions, additional diagnostic tools should be used. Only in the case of correctly identifying the cause of the failure and the failing component, it is possible to determine the correct solution to eliminate such consequences.

As for all other cases, it is believed that at least one of the above proposed methods will work. So it remains to advise you to use the troubleshooting options, moving from simple to more complex methods. But in any case, so that such excesses do not occur in the future, it is better to take care in advance of creating a system image or recovery disk, recording antivirus utilities etc. It's quite easy to do this, even with your own Windows tools... Such tools should be at hand for any user, as they say, in the most unforeseen case, because none of the currently used Windows systems are immune to failures.

If a serious problem occurs that prevents Windows from booting normally, the built-in wizard usually prompts you to perform a repair. However, if an error occurs during the recovery itself, the process may loop and the system will start the recovery on every new boot. Of course, reinstalling Windows will fix the problem, but you will lose all installed programs. It's good if you took care of creating a full system backup beforehand, but what if there is no such copy?

However, this is not a verdict yet. You can try to "knock out" the system from the recovery cycle using this instruction. All you need is a Windows installation disc and a little attention. After setting the BIOS to boot from external media, insert the disc and boot from it. A menu will appear Windows installations.

Run the bcdedit command in the console that opens.

This will give you a list of boot options. In the first block "Boot Windows" find the line resumeobject and copy the identifier located opposite it.

Now run the command bcdedit / set (GUID) recoveryenabled no, substituting (GUID) with your ID.

Therefore, automatic recovery will be disabled and the cycle will be interrupted. Deactivating the recovery procedure, however, does not correct the errors that caused it. Therefore, it is highly advisable to check file system by running at the command line chkdsk / r c:.

And if this does not give positive results, you can run the command sfc / scannow, aimed at restoring damaged system files.

You can also turn on the boot manager, called, as in Windows 7, by pressing F8 immediately after turning on the computer. To do this, in the running console, run the bcdedit / set (default) bootmenupolicy legacy command.

If all this does not help start Windows, most likely you will have to go to radical options - reinstalling or resetting the system to its original state.

Have a great day!

This article is devoted to the messages that appear on the "Automatic Repair" screen and inform the user that the operating system did not start correctly or the computer did not start correctly Windows 10. In this article, we will understand the reasons for their appearance and consider how to get rid of such messages and prevent their occurrence.

What to do first

When a notification appears that the PC did not boot correctly, you must restart the computer. In cases where the message pops up during system reboot due to interruption Windows updates, It helps.

The second thing that can become the source of the problem is the abnormal mode of operation of the power supply, as a result of which the hardware components operate in a mode that differs from their typical one. Due to two unsuccessful attempts to boot Windows 10, the latter calls the system restore function, thereby providing the user with a solution to the problem.

Drivers may be causing the problem. Think back or look at the latest drivers for which components were installed and roll them back.

If you see a message after resetting or updating Windows

A common algorithm, the execution of which leads to an error, is the following: turning on the PC after updating / resetting Windows is accompanied by a blue screen, and after collecting information, a window with options for restoring the operating system is launched.

1. In this case, go to "Additional parameters".
2. We call "Troubleshooting".
3. Again we go to "Advanced options".
4. Click "Launch Options".
5. Click "Restart".

After restarting the computer, the "Boot Options" will open, where, using the F6 key, we start safe mode with support for the command line.

We execute the sequence of commands:

• sfc / scannow - check system files with recovery of damaged ones;
• dism / Online / Cleanup-Image / RestoreHealth;

Appearance of the error "The computer has not started correctly"

It happens that, as a result of turning on the computer, an alert appears informing you that the computer / laptop is being diagnosed. The latter ends with a blue screen with the text "The computer has not started correctly" and a recommendation to open "Advanced options" after reboot.

This situation indicates that the system files are often corrupted in the registry.

The culprit of the situation are:

• power outages;
• the work of viruses or antivirus software;
• Windows 10 updates;
• deletion or incorrect values ​​of keys critical for the operation of the OS.

To solve the problem, do the following.

1. We go to "Additional parameters".

2. Click on the item "Troubleshooting".

3. Click on the button labeled "System Restore".

4. When the rollback point creation function is active, select one of the latest system snapshots and click "Next", then "Finish".

Resuming Windows 10 often solves this problem.

5. If the option is disabled (it should be enabled after the system returns to working state), a window will appear where you must select "Troubleshooting".

6. Click "Reset PC to its original state" in order to reset Windows 10.

7. Be sure to select the option with saving personal files (all files located on the C \: drive will remain in their own places after resetting Windows, but installed programs this does not apply).

Further actions can both correct the situation and aggravate it. Their implementation can lead to unexpected consequences. Following the steps below will put the system at risk, keep this in mind.

Using the command line, as in the previous method, we will check system files for integrity, fix damaged ones, and also restore registry files from a backup.

8. We execute the command "diskpart" in order to call the tool for working with partitions.

9. We enter "list volume" - the result of the command execution will be the visualization of the list of volumes of all disks connected to the PC.

10. In the list we find the system disk and the one reserved by the system and remember their letter labels.

11. Close the program by executing "exit".

12. Enter "sfc / scannow / offbootdir = F: \ / offwindir = C: \ Windows" and press "Enter".

Here: F is a system-reserved volume or drive (with a bootloader), C is a system partition.

13. "C:" - go to the system drive where Windows is located

14. "md configbackup" - create the "configbackup" directory.

15. "cd Windows \ System32 \ config \" - go to the appropriate folder.

16. "copy * c: \ configbackup \" - copy the previously created directory into it.

17. "cd Windows \ System32 \ config \ regback \" - go to the system folder "regback".

18. "copy * c: \ windows \ system32 \ config \" - copy the contents of the specified directory to the active one.

19. Press "A" for the Latin keyboard layout and "Enter" to confirm the overwriting of files.

These steps will restore the registry files from the auto-generated backup.

20. Close the command line window and click on the button with the text “Continue. Quit and use Windows 10 ".

With a high degree of probability, Windows 10 will start after performing this simple algorithm.

Cases of completely "killing" Windows 10 by manipulating the registry files are extremely rare, but they do happen. If this happened or the actions taken did not bring the desired result, one of two solutions remains:

• Reset Windows 10;
• Reinstall the operating system.

The first is done through the item "Troubleshooting" in the additional parameters. Even in critical situations, you can get there using the bootable media with the Windows 10 distribution.

In the second case, you will need a bootable USB flash drive and about 30 minutes of partial free time.

Restoring the Windows 10 boot loader must be performed if the operating system cannot be loaded on the computer. After starting the PC, an error message appears on the screen, indicating that it is impossible to boot the system for one reason or another.

The reasons for problems with the system bootloader can occur due to hardware and software... In this article, we will look at ways to restore the operating system bootloader that are not related to computer hardware problems, for example, with malfunctioning hard disk or RAM.

Some possible reasons Windows bootloader problems:

• unknown system failure;
• exposure to malicious software;
• incorrect user actions;
• shutting down the computer during the installation of updates;
• installing another operating system on a computer;
• the result of the work of programs for cleaning and tweaking the system.

If the user uninstalled the bootloader by their own wrong actions, or it does not work due to another problem, how can I restore it? It suddenly became impossible to load the operating system on the computer, how to restore the Windows bootloader?

To perform a Windows boot loader repair, if the automatic repair does not work, the command line, launched from the Windows 10 recovery disc, from the installation disc, or from. Therefore, I recommend that all users have bootable discs, which will come in handy in case of problems on the computer.

Simple failures are eliminated directly in the running system, and in case of serious problems, the OS may not boot. PC download done with bootable media(flash drive or disk), will allow you to call the system recovery tools to solve the problem.

Directly by means of the system, you can create on a USB flash drive or CD / DVD disc. To restore the system, you can use a bootable Windows USB flash drive or an installation DVD with the operating system.

The user can free from the official website and then immediately create. There are a large number of third-party programs for creating bootable USB drives.

Most reliable way system recovery in case of serious problems: for example, using system tools, and then from a backup copy. To create a backup image of the system, you can use third-party software:, ( free program) etc.

In this article, we will look at several ways to restore the Windows 10 bootloader, without using third-party software. The instruction is suitable for operating systems Windows 8.1, Windows 8, Windows 7.

To start boot from boot disk(USB flash drive or DVD), you need to enter the BIOS or UEFI boot menu, and then select the boot device. Another launch option: the choice in the BIOS settings of the boot priority from the bootable media. Different keyboard keys are responsible for entering the BIOS on computers, so first find out what to press, focusing on the model of your device.

Repair Windows 10 bootloader with automatic fixes

Using my example, we will try to restore the UEFI bootloader of Windows 10. The article is suitable for users with computers that have an MBR bootloader in Windows 10.

After downloading on the computer, in the first window of the Windows setup program, click on the "Next" button.

In the next window, click on "System Restore".

In the Select Action window, click on Troubleshooting.

First, I recommend choosing the Startup Repair method. The Windows operating system will fix problems that prevent the system from booting on its own. This is the simplest solution to the problem, I myself have used it more than once.

The operating system will automatically diagnose the cause of the crash and restore the system files required to boot Windows.

In case of a positive outcome, Windows 10 will start in normal mode on the computer.

If Startup Repair fails to recover your computer, you will need to use the command line.

Repairing the Windows bootloader via the command line - 1 way

After unsuccessful automatic recovery, in the "Startup Repair" window, click on the "Advanced options" button.

Alternatively, you can reboot from the bootable media (USB flash drive or DVD), and then go to the Advanced Options window.

In the "Advanced Options" window, click on the "Command Prompt" button.

We will perform a Windows boot loader repair via the command line. The bootloader recovery process will take place in two stages:

• using the Diskpart utility, we find out the name of the system disk on which Windows is installed;
• then we will create the boot files for the operating system.

In the command line interpreter window, enter the command to run the Diskpart utility (after entering each command, press the "Enter" key):

Diskpart list volume

In the list of disks (volumes) on your computer, you need to find the system partition on which the Windows operating system is installed. We need to find out the "Name" (drive letter), when searching for a volume, be guided by the size of the disk with the installed system. The operating system can be installed drive "C", "D", "E", etc.

In my case, the system is installed on the "C" drive.

To exit the Diskpart utility, enter the command:

Now you need to enter the command to create the operating system boot files using the bcdboot utility.

In the command prompt window, enter the command:

Bcdboot X: \ windows

In this command, "X" is the letter of the volume (drive) on which the system is installed on my computer drive "C", so I entered this drive letter.

After executing the command, you will see a message stating that the download files have been successfully created.

Close the command prompt window.

In the "Select action" window, click the "Continue" button to exit system recovery and continue using windows 10.

How to Repair Windows 10 Bootloader Using Command Prompt - Method 2

This method will use the command line invoked from the recovery disc, bootable USB flash drive, or from the Windows installation DVD. The computer needs to boot from a boot disk and then run a command prompt.

The Windows 10 boot file creation process will take place in three steps:

• using the DiskPart utility, we find out the number of the hidden volume (disk, partition) and the file system, format the disk, and then give a letter to the volume (disk);
• creating files on a hidden volume (disk) to boot the system;
• deleting a letter from a disk (volume) of a hidden partition.

In the command line interpreter window, enter the commands in turn (do not forget to press "Enter" after entering the appropriate command):

Diskpart list volume

A computer with GPT UEFI has a hidden partition with the FAT32 file system, it is not labeled with a letter, ranging in size from 99 to 300 MB. On computers with BIOS MBR, there is a hidden volume with the NTFS file system, up to 500 MB in size.

We need the volume number (Volume 0, Volume 1, Volume 2, etc.) and its file system. Pay attention to the letter of the volume (drive) on which Windows is installed.

Select a hidden volume, it does not have a "Name" (drive letter). In this case, it is "Volume 4", your computer may have a different volume number.

Select volume X

Enter the command to format the volume to the FAT32 or NTFS file system, depending on the UEFI or MBR hard drive partition style, respectively. On my computer, the hidden partition has the FAT32 file system, so I chose the option to format to this file system.

Format fs = fat32 or format fs = ntfs

Assign letter = Z

Exit the Diskpart utility:

Now you need to run the command to create Windows boot files:

Bcdboot C: \ Windows / s Z: / f ALL

In this command, "C" is the letter of the partition where Windows is installed, and "Z" is the letter of the hidden drive.

After the boot files have been successfully created, run the Diskpart utility again:

Diskpart

List the volumes on the computer on the command line:

List volume

Select the hidden volume that you previously assigned the letter "Z" to:

Select volume X

In this command, "X" is the hidden volume number on your computer. You already selected it on the command line when you assigned a name for this volume (partition).

Enter the command to remove the volume name (drive letter) and then exit the Diskpart utility:

Remove letter = Z exit

Close Command Prompt.

Remove the DVD or bootable USB drive from your computer, bootable media is no longer needed.

In the "Select action" window, click the "Turn off" button.

Turn on the PC, which will boot the Windows 10 operating system again.

Repairing the Windows 10 boot loader in Bootrec

You can use the Bootrec.exe utility to troubleshoot system startup problems on computers with MBR (Master Boot Record).

The main commands of the Bootrec.exe utility:

• FixMbr - Windows compatible master boot partition (MBR) record, existing partition table is not overwritten.
• FixBoot - writing a new boot sector compatible with Windows to the system partition.
• ScanOS - search all disks of installed systems compatible with Windows, displaying entries that are not in the system configuration store.
• RebuildBcd - search all disks of installed systems compatible with Windows, select systems that need to be added to the configuration repository.

In most cases, it is enough to write the master boot partition or a new one boot sector compatible with the current operating system.

After booting into Windows Recovery Environment. In the Command Prompt window, enter one of the commands:

Bootrec.exe / FixMbr Bootrec.exe / FixBoot

If the problem is not solved by the proposed methods, you can fix the problem using a "clean" system instead of the one installed on the computer.

Conclusions of the article

In case of problems loading the operating system, the user needs to restore the Windows 10 boot loader. To get the job done, you will need to boot to the computer from a bootable USB flash drive or from an installation DVD. Recovery is performed from the recovery environment automatically by means of the system, or manually by the user after entering the appropriate commands in the command line.

Experienced PC and Internet user

Restoring Windows 10 allows you to return the operating system to a working or original state from an automatically or manually created system rollback point or a complete system image stored on the hard drive.

Also in the toolbox "dozens" there is a tool for performing an OS reset, which will save you from a long reinstall Windows 10, and the creation of a recovery flash drive necessary to resume the functioning of the operating system in critical situations (when Windows 10 does not boot and does not provide an opportunity to get into the recovery environment).

The proposed instruction article tells about all the tools that make up the system recovery environment in Windows 10, the mechanisms of their functioning, how to use this or that function and the effectiveness of recovery methods in certain situations.

Before starting to study the material, it is recommended that you read the instructions on how to restore the operating system bootloader, check its files for integrity and restore damaged registry files.

Safe mode

The first thing to try when you encounter problems is to boot into Safe Mode. Let's consider the situation when the "ten" does not load and does not allow rebooting with the appropriate parameters (you cannot get into this mode via msconfig or special boot options).

1. We start from the bootable media with the Windows 10 distribution using the Boot Menu.

4. We execute the command "bcdedit / set safeboot minimal" for the subsequent start of the computer in safe mode.

5. Reboot by closing all windows.

After starting the computer, you can start solving the problem that prevents the normal start / operation of the PC.

We return the computer / laptop to its original state

The most notable recovery feature that came with Windows 10 is revert Windows to its original state. You can use it through the "Parameters".

1. Call the menu using Win → I.

2. Go to the "Update / Security" section.

3. Click on the "Recovery" tab.

This opportunity should be used as a last resort when the options below did not help solve the problem, because in the end you will get a clean, only installed operating system with or without personal data, depending on the specified parameters.

4. Click "Start", after which a dialog will appear prompting you to specify the parameters for resetting the operating system.

The first option is complete cleaning system volume from all files and quick reinstallation of the "dozens" without using the installation disk with the operating system distribution kit, the second method is fast Windows installation 10 with saving user files and settings of applications installed on the PC, the programs themselves will not be saved.

There is one more way to call the reset dialog of the operating system even without authorization in the system. Everything is done on the authorization screen. To access the function, press the "Restart" icon while holding down the Shift key. After restarting the computer, click on the "Diagnostics" icon, then click on the button to return the system to its original state.

The advantages of the method are that there is no need to have an installation disk / flash drive and all actions are performed automatically without any user intervention.

There is only one drawback - when the user deletes the system image or the location of this file in the damaged sectors of the hard disk, it will not be possible to perform a quick reinstallation, but here in the arsenal of the “dozens” there are several additional tools: using the system recovery disk if available (a very rare occurrence) and backup Windows 10 using OS tools on a non-system volume.

Windows 10 recovery flash drive

The tool is called a Windows recovery disk, but in the top ten it should be renamed into a recovery flash drive (we will use this very term).

If earlier in the OS from Microsoft there were utilities for performing automatic reanimation of the system, which in most cases only tried to do something, then in the top ten there is an option to create a system image for the subsequent return of the system volume to the state imprinted in this image by automatically reinstalling the OS , as discussed in the section above.

A similar image is created in the following way:

1. Call the Control Panel applet called "Recovery".

3. We mark the option of backing up system files to a recovery flash drive in order to be able to perform an instant reinstallation of the "dozens".

4. Upon completion of all write operations or, if necessary, boot from the created drive using the Boot Menu function.

5. In the action selection window, go to the "Diagnostics" section.

While in it, we will open the opportunity to perform the following operations:

• using a flash drive with an image, return Windows 10 to its previous state;
• visit the UEFI / BIOS options;
• to resort to resuscitation of the "ten" by means of the rollback point;
• run through the command line, for example, to create a copy of the bootloader on the corresponding volume;
• restore Windows 10 from a full OS image.

The presence of such a flash drive in the case of the "ten" is much more useful than even the installation one, although the latter allows you to start some of the operating system recovery operations on the screen with the "Install" button immediately after choosing the language.

We create a complete image of the system's resuscitation

Preparing for automatic recovery is to create a snapshot of Windows 10 at the time of its current state. It is best to create such an image immediately after installing the operating system with all the drivers and software, as long as the system volume is not littered, like the registry.

It is not necessary to form a snapshot in the first hours of the new OS functioning, this can be done a couple of days after reinstalling it, so that Windows gets used to it and is brought to a normal functioning state, but does not have time to acquire garbage files and registry keys.

1. The process begins with cleaning the C: drive from the system registry and uninstalling programs that were unnecessary.

5. Determine the storage location for the operating system snapshot and the partitions that will be backed up (it is best to specify a removable drive).

After the system files are compressed and transferred to the specified digital media it can be used to quickly revert Windows 10 to an imaged state. In order to start image recovery, you need to boot the computer from the USB flash drive on which the file is stored, or through the Windows 10 installer ("Diagnostics" - "Advanced options" - "OS image recovery").

Windows 10 rollback points

There are no innovations with this function, all its capabilities work as in previous versions of the OS. It provides a chance to return the system to one of the preserved states through the recovery environment or in a running operating system. To take full advantage of the feature, it must be activated. You can check the status through the Control Panel applet under the name "Recovery". In the window, click "System Restore Settings".

To change the parameters, click "Configure" and specify the space allocated for storing rollback points on the system disk.

When using a licensed image, this function is activated, but if you installed Windows 10 downloaded from pirated sites, the author of the assembly may have deactivated this function. How do I enable System Restore? Select the system partition, click "Configure" and move the checkbox to the "Enable system protection" item.

Typically, rollback points are generated automatically when the user or any application makes changes to system files, settings, services and registry settings. The option to manually create restore points is also available. In the "System Properties" window, click "Create" and enter the name of the snapshot to make it easier to identify it.

To operate the system rollback function through one of the restore points, go to the same applet and click "Start System Restore". In the case when Windows 10 does not start, we boot from a recovery disc or installation distribution kit and call "System Restore" through "Advanced options" in the diagnostic window.

File history

Another innovation in Windows 10 that allows you to make and store backups the specified files (often text documents and various projects) and extract the necessary copy of the file from the reserve, if necessary.

As you can see, the "top ten" has an extended set of effective functions to return the system to a working state in any cases and without reinstalling the OS. In addition to all the listed tools, you should definitely include the function of repairing the bootloader using Windows 10 tools.
