operating room Windows system 10 from Microsoft is quite reliable and I don’t have any particular complaints - you still have to try hard to break it. However, cases are different, and therefore today I want to talk about the main mistakes when booting Windows 10 and ways to fix them. In more than half of the cases, restoring the system boot and normal operation is quite possible - you just need to remain calm and correctly follow the instructions below.

Black screen when starting Windows

This is perhaps the most common Windows 10 boot error, which every third user has encountered at least once. Black screen with no signs of “life” operating system may be accompanied by the appearance of a cursor on the display or without it at all. It is pointless to wait longer than 15-20 minutes for the system to start successfully - the desktop will not appear. The most common cause is a failure of some drivers or their incorrect installation. In this case, it is not at all necessary that you did the installation yourself - some programs, as well as the Update Center, can do this.
The solution in this case is to start the OS in Recovery mode, booting from the Windows installation flash drive. Open the section Diagnostics, in the next window click on Additional options and then - System Restore.

After this, you will see a list of available recovery points. Select the closest one in time and click the “Next” button.

Only here in the additional parameters select the “Startup Recovery” section.

If you can’t restore normal operation, try the following advice.

Error “The computer is not started correctly”

In this situation, Windows 10 cannot boot, but at least it does not lose control of the computer and signals to the user that the computer is not running correctly.

You can, of course, click on the “Reboot” button, but as a rule this does not give any result (if sometimes it boots normally and sometimes not, check your hard drive).

To correct the situation, you need to click on “Advanced options”, and then go to the section Troubleshooting > Additional options > Boot Options and here click on the “Restart” button. After this, the following menu should appear:

Press the key 6 or F6 to launch Windows Safe Mode with command line support.
Your PC should restart again and boot into Safe Mode. In this case, there should be a command line window on the screen. Enter the following commands one by one:

Sfc /scannow dism /Online /Cleanup-Image /RestoreHealth shutdown -r

The last command will again lead to a reboot and Windows should still start normally.

Operating system not found

This is the saddest option of all. The computer simply does not get to the point of loading Windows and writes errors like this on a black screen.

First: “Boot failure. Reboot and Select Proper Boot device or insert boot media in selected boot device."

Second: “An operating system wasn't found. Try disconnecting any drives that don’t contain an operating system. Press Ctrl+Alt+Del to restart".. In order to restore it you will need again installation disk. Go to the section bootrec /RebuildBcd bootrec /fixMbr bootrec /fixboot

This way we will overwrite the bootloader files. Restart the PC and check the system operation.

3. Hardware damage hard drive . Well, this is the saddest, and most importantly, expensive option, since you will have to buy a new hard drive.

Some users are faced with such a critical situation when the computer does not start correctly with Windows 10. At the first stage, before taking any specific measures, it is worth finding out what is the cause of the problem you have identified.

The situation occurs when you try to turn on the computer. Instead of the normal course of this process, you are faced with an inscription notifying you that it is impossible to complete it.
There can be many reasons for these types of warnings:

• problems with system files;
• error caused by interruption during execution necessary updates systems;
• hardware problems (for example, problems related to the state of the power supply);
• incorrect driver status;
• function related errors fast loading.

It is clear that if something is wrong with separate elements equipment, then here you will have to deal with identifying breakdowns, and then eliminating them associated with their repair or replacement. This is exactly what you should do if your power supply is faulty, when the device is not able to receive the energy it needs to operate.
Quick start mode allows you to reduce the duration of the process from turning on the device to its immediate readiness for operation. However, unexpected problems may arise here due to the fact that the computer is simply not started correctly. The solution if your computer is not starting properly is to simply uncheck the appropriate option, which you will be able to see among the system parameters related to power status that you will find in the Control Panel.


Problems with drivers require using more stable versions and reverting to older versions. For example, problems may be associated with a special driver from the Intel brand, which is responsible for controlling the entire machine. If you install something on your computer, use only those options that you purchased directly from the official Windows resource.

Automatic recovery if the computer does not start correctly on Windows 10

If it turns out that Windows computer 10 launched incorrectly, then you need to understand how to correctly fix it. Let's consider the first option, associated with damage to the most important system files.

When a warning appears that Windows is not running correctly, typical options will be offered further actions. The easiest option is to turn off and restart your computer, however, unfortunately, this does not always have good consequences. If this path does not help, you should use an alternative by changing additional settings for starting Windows if the computer did not start correctly.

The machine itself will search for errors if you use the appropriate option. There are two possible actions here: or try to restore the system to a certain point, which is called a control point. Another option is to simply reinstall Windows environment on the equipment.

If a Windows 10 computer is not running correctly, what should the user do in such a critical situation? In the second case, we are dealing with an interruption associated with updates to the system used on your equipment.
Do not rush to resort to extreme measures, but delve a little into the settings that are responsible for the boot parameters that are offered if your Windows computer is not running correctly.


Once in the appropriate section, use the F6 key to be able to administer in command line format. It's worth tinkering with some commands here. Write them sequentially in three lines, using slashes as a separator.

• sfc/scannow
• dism/online/cleanup-image/RestoreHealth
• shutdown –r

If you are not computer savvy, it is better to entrust such an operation to a more experienced person who will save your computer if it was launched incorrectly. These processes do not always lead to the desired result, and their implementation can take a long time, accompanied by additional errors, which will only lead to unnecessary nerves for a beginner in this matter.

Extreme measures

If a computer running Windows 8 does not start correctly, then alternative option automatic recovery will occur.
Alternatively, you can simply try to reinstall Windows again if the computer does not start correctly, but to do this you must have the files with this system, as well as copies of all your important data on another medium so that they are not destroyed. Try reinstalling while saving important files, but this option is not always successful if the computer was not started correctly.

To save the information at least partially, try rolling back your software to a breakpoint in Windows. By clicking on the recovery option, if the system does not start correctly, just watch what is happening: most likely, the machine itself will create the necessary point and perform all the required actions. As a preventative measure, you can try setting settings for such cases.

The Microsoft community advises creating triggers with a given frequency for these purposes, finding them in the SystemRestore section. It refers to the “Task Scheduler”, which is located in the Control Panel. You can find the files created in this way in the information section about the system volume on the main disk. You can create new points every day or at any other frequency that interests you, while the earliest of them will be gradually deleted so as not to take up extra memory.

Have a great day!

This article contains the most common errors when starting Windows 10, as well as how to fix them. We hope this information will make life a little easier for those who have switched to new version system and suddenly found himself between a rock and a hard place.

1. Windows 10: “The computer is not starting correctly”

The first common problem when starting Windows 10 is that the system reports a certain critical error(CRITICAL_PROCESS_DIED, INACCESSIBLE_BOOT_DEVICE) and then displays a blue screen " Automatic recovery" with the text "The computer is not started correctly." The cause of this error, in most cases, is damage and deletion of system files or registry entries. This may be caused by installing and uninstalling programs, or by antivirus programs or Windows registry cleaning utilities.

The solution to the problem is to repair files and registry entries that are damaged: Click on the Advanced options button on the blue screen, select Troubleshooting > Advanced options > Boot options.

Click Reboot.

In the Boot Options window, press F6 or number 6 on your numeric keypad to launch safe mode with command line support.

The computer will restart in Safe Mode and Command Prompt will automatically open. In it, enter: sfc /scannow dism /Online /Cleanup-Image /RestoreHealth shutdown -r The computer will restart and after that Windows startup will be carried out as normal.

Another known problem is that the system boots all the way to the Windows logo, after which the computer randomly shuts down. The reason for this error is also damage to system files, however, unlike the first case, the damage is so serious that the system cannot start the recovery itself.

In this case, you will have to create a rescue disk Windows recovery on another Windows 10 PC: In the panel Windows management 10 Find and select Recovery > Create a recovery drive.

In the window that appears, set the Run option backup system files to the recovery drive and click Next.

Connect an empty USB drive to your computer. Select it in the recovery disk creation window and click Next > Create. Wait until the files are copied and click Finish.

Remove the USB drive from your computer, connect it to the one that won't run Windows 10, and enable booting from it in the BIOS.

The Windows Recovery Environment will launch. In it you need to select System image recovery, or Command Prompt, and then enter the commands from the instructions for solving the first problem. You can also run System Recovery Environment from the disk you installed Windows from. To do this, you need to boot from the installation disk, in the bootloader instead of Install, click System Restore. From the menu that appears, select Troubleshooting > Advanced Options. The same options window above will open.

After recovery, the computer will restart. Return to BIOS loading from the hard drive, and the system should start correctly.

3. Errors “Boot Failure” and “An operating system wasn’t found”

In some cases, when starting Windows 10, instead of loading the operating system, a black screen appears with one of two errors: Boot failure. Reboot and Select Proper Boot device or insert boot media in selected boot device.

An operating system wasn’t found. Try disconnecting any drives that don’t contain an operating system. Press Ctrl+Alt+Del to restart. There can also be two reasons for this error: Incorrect boot device order in BIOS or UEFI. Make sure you are booting from the exact drive where Windows 10 is installed.

Damage to the system bootloader. In this case, you will also need an installation disk or a Windows 10 emergency recovery disk. After booting from it, in the recovery environment you need to select Startup Repair and let the bootloader files be overwritten. The problem may also be hardware damage to the hard drive from which the boot is made. 4. Windows 10 won't start: black screen

A common error when starting Windows 10 is a black screen with no signs of loading the desktop, with or without the cursor frozen on the screen. This often happens as a result of incorrect installation of any drivers: after rebooting, the computer works, but the OS does not load. In most cases, the solution to the problem lies in a system rollback. To do this, you will also need an installation disk or a Windows 10 emergency recovery disk. After booting from it, in the recovery environment, you can try selecting System Restore.

This will roll back the system to the state before the problem occurred. The system will prompt you to select a restore point to which to rollback, and after confirmation it will perform it. As a rule, after a reboot the black screen disappears. 5. Long loading time Windows 10 on startup

There is a situation when Windows 10 does not load, the waiting icon is spinning, and that’s it. In fact, most likely, nothing bad is happening - the system is simply installing the updates that it downloaded the last time you used the computer. In this situation, the best thing to do is just wait. This condition may last for several hours depending on the number and volume of downloaded updates. It is recommended not to turn off the computer, but to leave it in the boot state for 1-2 hours.

To prevent this error from happening again when starting Windows 10, you can set your computer to update on a schedule, and the system will not download updates without your knowledge. To learn how to edit update policies, read our instructions for setting Windows 10 active period.

This instruction will describe step-by-step ways to fix the problem when, when loading Windows 10, on the Automatic Repair screen, you see a message stating that the computer did not start correctly or that the Windows system did not boot correctly. We'll also talk about possible reasons such an error. First of all, if the error “The computer is not started correctly” occurs to you after turning off the computer or after an interruption Windows updates 10, but is successfully corrected by clicking the “Restart” button, and then appears again, or in cases where the computer does not turn on the first time, after which automatic recovery occurs (and again everything is corrected by rebooting), then all the actions described below with command line - not for your situation, in your case the reasons may be as follows. The first and most common is power problems (if the computer does not turn on the first time, the power supply is probably faulty). After two unsuccessful startup attempts, Windows 10 automatically launches System Restore. The second option is a problem with turning off the computer and fast boot mode. Try it. The third option is that there is something wrong with the drivers. It has been noticed, for example, that the rollback Intel drivers Management Engine Interface on laptops with Intel over old version(from the laptop manufacturer's website, not Windows 10 Update) may solve problems with shutdown and sleep.

The computer does not start correctly in Windows 10

This instruction will describe step-by-step ways to fix the problem when, when loading Windows 10, on the Automatic Repair screen, you see a message stating that the computer did not start correctly or that the Windows system did not boot correctly. We’ll also talk about possible reasons for this error.

First of all, if the “The computer did not start correctly” error occurs to you after turning off the computer or after interrupting the Windows 10 update, but is successfully corrected by clicking the “Restart” button, and then appears again, or in cases where the computer does not turn on the first time , after which automatic recovery occurs (and again, everything is fixed by rebooting), then all the actions described below with the command line are not for your situation, in your case the reasons may be as follows.

The first and most common is power problems (if the computer does not turn on the first time, the power supply is probably faulty). After two unsuccessful startup attempts, Windows 10 automatically launches System Restore. The second option is a problem with turning off the computer and fast boot mode. Try turning it off quick start Windows 10. The third option is something is wrong with the drivers. It has been noticed, for example, that rolling back the Intel Management Engine Interface driver on laptops with Intel to an older version (from the laptop manufacturer's website, and not from Windows 10 Update) can solve problems with shutdown and sleep. You can also try checking and correcting the integrity of system Windows files 10.

If the error appears after resetting Windows 10 or updating

One of the simple options for the error “The computer has not started correctly” is something like this: after resetting or updating Windows 10, “ blue screen» with an error like INACCESSIBLE_BOOT_DEVICE(although this error can be an indicator of more serious problems, in the case of its appearance after a reset or rollback, everything is usually simple), and after collecting information, the “Recovery” window appears with the “Advanced options” button and reboot. Although, this same option can be tried in other error scenarios, the method is safe.

Go to “Advanced Options” - “Troubleshooting” - “Advanced Options” - “Boot Options”. And click the "Restart" button.

In the Boot Options window, press 6 or F6 on your keyboard to launch Safe Mode with Command Prompt support. If it starts, log in as an administrator (and if not, then this method is not suitable for you).

In the opened command line use the following commands in order (the first two may show error messages or take a long time to complete, freezing in the process. Please wait.)

1. sfc /scannow
2. dism /Online /Cleanup-Image /RestoreHealth
3. shutdown -r

And wait until the computer is restarted. In many cases (in relation to the problem appearing after a reset or update), this allows you to fix the problem by restoring Windows 10 to start.

"The computer did not start correctly" or "Windows appears to have started incorrectly"

If, after turning on your computer or laptop, you see a message stating that the computer is being diagnosed, and after that a blue screen with a message stating that “The computer is not started correctly” with a suggestion to restart or go to additional settings (the second version of the same message is at "Recovery" screen shows a message that the Windows system did not boot correctly), this usually indicates damage to some Windows 10 system files: registry files and more.

The problem may appear after a sudden shutdown while installing updates, installing an antivirus or cleaning the computer from viruses, cleaning the registry using cleaner programs, or installing dubious programs.

And now about ways to solve the problem “The computer is not started correctly.” If it so happens that you have automatic creation of restore points enabled in Windows 10, then first of all you should try this option. You can do this as follows:

After clicking the cancel button, you will be taken to the blue screen again. Click on “Troubleshooting” on it.

Now, if you are not ready to undertake everything next steps to restore startup, which will use exclusively the command line, click “Reset the computer to its original state” to reset Windows 10 (reinstallation), which can be done while saving your files (but not programs). If you are ready and want to try to return everything as it was, click “Advanced options”, and then “Command line”.

In the command line, we will check the integrity of the system files in order and Windows components 10, we will try to fix them, and also restore the registry from backup copy. All this together helps in most cases. Use the following commands in order:

There is a good chance that Windows 10 will start after this. If not, you can undo any changes you've made in the command line (which you can run the same way as before or from the recovery disk), restoring the files from the backup we created:

1. cd e:\configbackup\
2. copy * e:\windows\system32\config\(confirm overwriting files by pressing A and Enter).

If none of the above helped, then I can only recommend Windows reset 10 through “Reset the computer to its original state” in the “Troubleshooting” menu. If after these steps you cannot get to this menu, use a recovery disk or bootable USB flash drive Windows 10 created on another computer to get into the recovery environment.
