How to reinstall Windows 7

Until the arrival of Windows 10, Windows 7 represented the most successful and appreciated operating system from Microsoft. Although the company currently no longer provides support for this version, there are still many users with computers that incorporate it and that are functional for their activities. In that sense, we want to teach you how to reinstall Windows 7 on any computer without too many complications.

It is a fairly simple process, for which, however, you will need to be informed of certain aspects in order to achieve it successfully.

What do I need to reinstall Windows 7 on a computer?

First of all, those who are looking for how to reinstall Windows 7 should know that the only alternative is a clean install. Years ago, when Windows 10 was taking its first steps, it was possible to go through the process of going back to the old operating system if you had upgraded from Windows 7. Right now it is no longer possible, since Windows 10 has received a whole number of updates and Version changes that are no longer compatible with restore.

On the other hand, you will need to have a USB memory of at least 8GB or a DVD disc. The most recommended option is the first one, however, installing from disk can get you out of trouble if you don't have USB ports.

Additionally, you will have to do a previous search to know how to enter the BIOS of your computer so boot it from the installation media. This is usually achieved by pressing F2 or F1 on boot up, however this can vary depending on the manufacturer.

Considerations before reinstalling Windows 7

The first thing to consider is that If the computer you want to reinstall Windows 7 on has a higher operating system, your files will not be preserved. In this way, the only alternative you have is to do a clean installation, where everything will be removed.

However, if you are looking for how to reinstall Windows 7 on a computer that already has the same operating system installed, then you can keep the files and find them in the Windows.Old folder that will be created during the process.

Step 1: Download an ISO Image

The fundamental piece for this task is an ISO image of Windows 7, however, there is an obstacle in front and it is the fact that Microsoft has withdrawn the possibility of downloading from its official site. This forces us to resort to third party websites, so we recommend paying close attention to the file you are downloading, identifying that it is in ISO format and that its weight is 3GB.

Step 2: Create Bootable USB or DVD

Once you have the ISO image of Windows 7, we must insert it on a DVD or USB and make it bootable. Burning the image to a disc is really simple, you just need to insert the blank DVD and then right click on the ISO image. Immediately, Select the “Burn Image” option and a window will be displayed where you can start recording the disc.

Step 3: Boot the computer from the DVD or USB stick
