Although the title of the article is how to install Windows 7 from a flash drive on a laptop, the same method is used to install Windows 8, Vista or XP.
Why did I decide to write about this, since there are plenty of materials on this topic on the Internet? The thing is that I have never tried to install with windows flash drives on a laptop (netbook) - there was no need.
And just recently, an acquaintance approached me with a request, or rather for advice, why Windows 7 was not installed on his laptop.
The reason turned out to be drive failure. I decided to help him and install from a flash drive. I turned to the search engine for information, but according to the instructions written there, I could not install the operating system via a flash drive.
I had to experiment. That’s why I decided to describe the installation process; I think I’m not the only one who had problems.
I should immediately note that the laptop was old (more than 10 years), but the installation was successful. True, in some “antediluvian” it may not work out ( motherboard this option may not be supported).
I’ll also say right away that I’ve come across a statement online that if the flash drive is 3.0 and usb 2.0, then the laptop won’t see it during installation. This is not true, I just installed with 3.0, on an old laptop with usb 2.0.
So, what do you need to install windows from a flash drive (memory card)
- Flash drive of at least 4 GB (memory card).
- Operating system image in ISO format.
- WinSetupFromUSB program.
Program for installing Windows 7 on a laptop via USB flash drive
First you need to write down Windows image 7 per flash drive. The network offers to use special programs or the standard method. Last method For inexperienced computer owners, it can be dangerous.
After my experiments, I settled on the “WinSetupFromUSB” program. It is free and the old versions are translated into Russian.
I used the latest (English - everything is clear without words) version and I recommend it to you. Where and how to download/install the program - what is written below is a little outdated (meaning downloading from the official website).
Now, after downloading, you need to install it. There will be two: for 32-bit laptops and 64. Run the one that matches the bitness of your operating system.
After launch, the program will immediately determine which flash drives you have enabled and display them at the very top. You will need to check two boxes (the first one, if the flash drive is formatted, is not necessary; the second one is next to the version of Windows being installed).
Then (when the checkbox is checked), on the opposite right side, an icon will become active, by clicking on which you can tell the program where the Windows image in ISO format is located.
When you’ve done everything, calmly click on the “GO” option at the very bottom - the program will do everything on its own (format the flash drive and write a disk image). See fig.
Setting up a laptop's BIOS to install Windows 7 or 8 from a flash drive
This is where the most crucial moment begins. I can’t even describe it exactly, because there are so many models of laptops or netbooks: ASUS, HP, Acer, MSI, Toshiba, Dell, Samsung, Lenovo, Sony, eMachines, Fujitsu, Apple, Notebook, LG, IBM, Compaq, Intel , BenQ, DEPO, Medion, Clevo, NEC, Gigabyte, Gericom, Packard Bell, Gateway, Matsushita (each of them has a unique installation from a flash drive).
Bios is also not the only one. This could be American Megatrends (AMI), Award Software or Phoenix Technologies. First of all, you need to enter it, although not always (you can try to start installing windows, immediately after burning the image to the flash drive, just read the article to the end).
Nobody can tell you exactly how to enter the BIOS of your laptop and configure it to boot from a flash drive. Even if you have, for example, two Acer laptops with the same BIOS versions, but different motherboards, the settings may differ significantly.
Only experiments with your laptop will help you choose the right solution. You won't have any problems logging into its BIOS. Usually, immediately after turning on, diligently press the key: F1, Esc, F2, F10, Del or Alt combinations+ F1, F10 = Setup. If that fails, experiment with the very top row of keyboard keys.
Not everything is simple here either. It would be good if there was a USB HDD item, as in the picture below.
But this doesn’t always happen – I didn’t have it. Other lines may also be responsible for loading from a flash drive, I had “remowable device”, but they could even turn out to be “innostop” and who knows what else.
Don't look at the floppy, it's a different drive. In a word, experiment here again. When you find it, click on it (press enter) and put it first in the list.
Then press F10 and enter. The laptop will begin to reboot. In theory, the download would start from the flash drive, but this did not happen for me (perhaps it will be different for you).
To start installing Windows from a flash drive, I had to press the “ESC” key immediately after turning it on. Then a window appeared asking you to choose where the computer should start booting from.
I pointed to the flash drive. Then another window appeared as in the figure below.
If you have the same thing, then click on the first one and it will immediately start on your laptop from a flash drive (by following the link, you will find out what to do next).
TIP: if something doesn’t work for you with the BIOS settings, write “BIOS pictures” in the Google search engine and when you find a picture like the one in your BIOS, follow this image to the site.
Most likely you will find it there detailed description, if not, describe the problem in the comments - we will find a solution together.
That's all. No one will describe it to you exactly step by step, just look at the pictures and press the appropriate keys.
Each laptop has its own configuration, and without your own experiments, you are unlikely to be able to install Windows from a flash drive. Good luck!

Do you have a problem reinstalling Windows on your netbook? This step by step guide will help you cope with this task without much effort. Any user, even a beginner, can do this by reading the instructions provided. So, what is reinstalling Windows, and how to do it correctly, without the help of a specialist?
To reinstall Windows yourself, you need to start with preparation. First we have to take care of the information we already have on the hard drive.
Preparatory stage
These instructions can be used for various models of netbooks from manufacturers Lenovo, ASUS, Acer and others. In principle, the described process will also apply to regular desktop PCs.
Before you start reinstalling the OS, you need to save the valuable data on your netbook that you have accumulated while using the old operating system. You can transfer them to external hard disk or flash drive of suitable size depending on the size of the information that needs to be saved.
It is important to remember where valuable data may be located. For example, if the current system is more old version Windows, for example XP, then you should look at the contents of the desktop, the “My Documents” folder. It is also possible that you have once saved something directly on the system drive, usually drive C.
Of course, list everything possible options, where important data may be stored is very difficult, but we will still give good advice: look through everything carefully, so that later you do not regret some forgotten photograph that captured one of the pleasant moments of your life.
Why is this necessary? The fact is that our task is to perform a complete reinstallation of Windows, and this implies the need to format the partition where we will install the new system.
Why is it recommended to completely reinstall Windows rather than update it? Everything is simple here. While using the previous OS, viruses may have accumulated that are sitting in files that you don’t even know about. For this reason, most experienced users practice a complete reinstallation. Let’s say right away that if accumulated viruses are the only reason why you are thinking of reinstalling Windows, then you should think about whether this is really the last option, because you can often get rid of malware in easier ways.
Determining the bit depth of Windows
Before you start installing a new system, let's talk a little about the bit capacity of the system on which you are planning to reinstall the current OS. Please keep in mind that Windows can be 32-bit or 64-bit. Among other things, these versions differ in that the 32-bit architecture cannot address more than 4 GB of RAM. We also immediately need to decide which Windows we will install - licensed or not.
- Inability to install system updates
- Embedded viruses and other malicious software
- Deactivated services
- Various Windows errors, which you will not find out about right away, and many other troubles
Using a flash drive as a carrier for the installation distribution
To install Windows on a netbook, we need a flash drive, since netbooks, due to their compact size, do not have a device for reading CD or DVD discs. In fact, many seem to have an even simpler option. After all, you can reinstall the system from this type of media on almost any computer, be it a netbook, laptop or just a desktop PC. USB sockets are available on all modern computers.
Making a bootable USB flash drive
Of course, simply copying the contents of the Windows distribution to a flash drive will not work. Additional operations must be performed, otherwise reinstalling Windows on the netbook will not work. But there is nothing complicated here, just place the image of the system you want to switch to on a flash drive. For this there are special programs, for example, you can use such a popular tool as UltraISO:
As soon as the image new Windows will be recorded on the USB flash drive, you can begin installing the system. Let me remind you once again that you must first save all important information from the system disk. There will be no such opportunity again.
Now we reboot our netbook and go into the BIOS, for which at the very beginning of the computer boot we need to have time to press F12or the Delete key.
Here you need to specify booting from a flash drive as the first priority.
As soon as we have done this, we exit the BIOS saving the settings made, after which the netbook will reboot again. Next, loading from the flash drive should begin and, accordingly, .
Installation process
At this stage, the Windows installer and the initial window of the first step of system installation should already load. For different versions Windows steps may vary slightly, but in quality general rule We can give the following recommendation: you should not immediately click next without familiarizing yourself with what the next step is. As a rule, at one of the installation stages you will need to check and, if necessary, specify the correct date, time, time zone, language settings, and so on.
The only step you don't have to dwell on is acceptance. license agreement, which contains standard text, which probably doesn’t make much sense to read.
It is important not to make a mistake at the stage where you will be asked to select the installation type:
- update
- full installation
We must definitely indicate the second option " Full installation", since we want to do a clean system installation, and not an update of the old OS, as was mentioned at the very beginning.
After this, a window will open to select the partition where you want to install Windows. Here we can safely indicate the partition on which our current one is installed old system, after which the specified formatting will be performed logical drive. Of course, we have already saved all the important information from the system disk and will not lose anything during the formatting process.
After formatting is completed, the OS installation process will begin. This usually takes 30-60 minutes on netbooks due to their low performance, although it can go faster if you have a more modern and powerful computer.
When the installation is complete, already new system Windows will ask you for your name, as well as an optional administrator password.
You may then need to make additional settings, such as network settings. Here, in most cases, you can agree with the recommended parameters, so that later they can always be changed from the operating system interface.
Let me also remind you that Windows will not always be able to find drivers for all devices on your netbook, so you will need to check which drivers were not found and install them for the system to function properly.

- Acer, Asus, Samsung, Lenovo - F2;
- hp - F10 + Esc .
If the brand of your device is not in this list, then find out the actual key for it on the window that loads when you turn on the PC.
The BIOS interface from different manufacturers is not similar in appearance, but the sequence of actions for changing the boot priority is almost identical. Navigation through the windows of a running BIOS of all versions is carried out using the arrows on the keyboard and the Enter, Esc, +, - keys.

Reinstallation from a flash drive
