As you know, the Windows operating system needs to be updated at least once every 12 months. And no matter how powerful your computer may be, all the same, in a year it will become buggy, freeze, or “crash”. Perhaps it is all about the viruses that inhabit the system and your antivirus will not recognize them. But most often the OS itself is aging, along with drivers and all other programs. There is only one solution - uninstalling and installing the new OS on the computer.
You will learn how to remove Windows 7 from your computer and install a new one during this article.
About reinstallation
So, let's say you have a computer that suddenly started to fail. If the statute of limitations for installing the OS is more than 6 months, it is best to install a new one in its place. To do this, you will need an image of Windows 7. Here you have two ways - to purchase the original or download "pirate". Both methods are almost identical - the first is more reliable, but expensive, the second is absolutely free, but not the fact that exactly what you want is installed. You should also carefully look to see if there is a license key for this image.
If it doesn’t exist, or you just forget to copy it to a notepad, you won’t be able to completely install Windows on your computer. But all other files remaining on the "C" drive (where the OS is installed) will disappear during uninstallation.
What about a laptop?
If this is a laptop, then you can look at the key to the operating system on its back side. In the case of the "pirate" such a trick will not work. Here you need to pre-record the key and enter it separately during installation. If the inscription on the back of the laptop has been erased, you can find the password on the Web.
How to remove Windows 7 from a computer if you do not have the original installation disk?
The lack of an original installation disk is not a problem for an advanced user, because you can download a pirated version of the "original" iso image of "Windows" on almost any corresponding site. If you want to remove Windows 7 from your computer, remember that the key to the “pirate” can go different, so be very careful - write down the password that is indicated with the link to the archive from the OS.
Now download the program to write the image to disk. You can use the ImgBurn utility for this. After it has downloaded, install it on the PC, take a blank DVD + R (or RW - it doesn’t matter) and insert it into the rum. After that, open the recording program, click Browse and select the "Windows Image" item. Press "open", set to the minimum speed and wait until the utility writes the file.
Next, you will see a window with information that the disc was successfully burned. Click “OK” and remove the DVD + R from the rum. Do not be alarmed if the disc drives out automatically after recording - this is how the program works. The first step is completed. Now about how to remove Windows 7 from the computer.
First of all, set the BIOS value to “First boot device CD-Rom”. You must first restart or shut down the computer and press delete. In some cases, you can also use the F1, F2, F8, and Ins keys. In order to avoid confusion, on the screen of its monitor, the program itself will tell you which button should be pressed to enter the BIOS.
How to understand that you are already in BIOS?
Here you will see a blue screen with white characters. Now we set the I boot from disk. To do this, on the arrows, go to Advanced Bios Features, then on First Boot Device and select CD-Rom.

Now go to save & exit setup, press enter, Y, and then enter again.

After some time, the computer will require you to press a key on the keyboard (Press any key to boot from Cd). Choose any, even a gap - this does not change the essence of the matter. Next, a black screen appears with the OS installation strip.

After a black screen with a loading bar, a window with the inscription "Windows is loading files" should pop up. Here you need to wait a few minutes until a window appears with a choice of language. You will have to wait 5 to 10 minutes.
Now, with the arrows on the keyboard, we get to the “Install” item and press enter.
At the same time, when the window with the "License Terms" appears (this is approximately 5-6 minutes after pressing "enter"), check the box there. Then press the enter key again.
We select the item "Full installation", select the installation disc with the recorded image. Click "Disk Settings" - "Format". This is where the main thing begins - all files that were previously located on the local C drive are uninstalled. How to remove a second Windows 7? Everything happens similarly to the above method. All processes and stages occur according to a similar principle, therefore, problems with this should not arise. Now you know how to completely remove Windows 7.
Useful advice
For 12 months of working with a computer, each of us accumulates a lot of files and information that we save on drive “C”. Therefore, to see them again after the "resuscitation" of the OS, copy them all to a safe place. This place can be either a USB flash drive or a local “D” drive, files in which are not deleted when reinstalling Windows. As practice shows, the latter option is more convenient and simple, since a flash drive often may not have free space for your data. Therefore, move all important documents to disk “D”.
And for the future, install all the programs there and store all the files, and bring shortcuts to the desktop. So there will be much less trouble when installing new drivers, programs and everything else.
Windows Uninstall
How to remove Windows 7 from a computer? After clicking the “Format” button, the system will automatically clean the “C” drive from all files - necessary and unnecessary, old and new. The OS itself is also deleted. In time, all this will take about 20-30 minutes. At this point, you can go make a cup of coffee or just watch how the computer deletes data. In any case, no action is required until the disk is formatted.
When the disk formatting is completed, you will see a window with fields for entering a user name on the screen. Here we need to enter a name, password (optional) and product key. If you accidentally clicked “Next” and did not enter the key, the computer will ask you to enter it again, but a little later. Now you need to choose one of the three points for updating. You can choose any, but, as practice shows, the first will be most suitable.
We define the time zone and wait a few minutes until a window with “Windows 7” appears on the screen.
Now you will know exactly how to remove the old Windows 7 when reinstalling the OS. As you can see, there is nothing complicated here - most of the operations are performed by the computer itself. The main thing is to pre-copy all the important files and folders to the local D drive, otherwise all of them together with the operating system will be permanently deleted.
