How To Reinstall Windows 10 On Your PC- A Brief Guide!

There are plenty of reasons why users have to reinstall the Windows OS and one of them could be yours. Let’s say the PC is infected with malware and viruses and you can’t get rid of them in spite of using all the possible antivirus solutions. In that case, reinstallation is the only available choice.

Over a period of use, your PC gets slower. That’s partly because of hardware wear and tear and largely due to the junk files, bad registry entries, unwanted shortcuts and more. While there are many PC tune-up applications that claim to rid your computer of all these unwanted items, they can go only so far. Reinstalling windows speeds up your computer rather magically.

If your computer is too slow, there could be a problem with hardware. But, that’s rare. And, even if there is a hardware issue, reinstallation of Windows 10 will make your PC faster than before.

You will also need to reinstall the OS when there is a hard disk failure and you need to deploy a new one (or you are moving on to a bigger, better hard disk).

So, if you have a reason, we have a solution. In this article, we will guide you through the complete Windows 10 reinstallation process.

There are more than one ways to reinstall Windows 10 on your PC. We will discuss reinstallation process using Media Creation Tool in this section. It is Microsoft tool, which is primarily used for installation and reinstallation of various versions of Windows OS. You can download this free tool from

You will need Microsoft Account sign in to download this application. If you don’t have an account yet, create one by clicking on ‘Sign in’ link on the top right corner of this page and then by clicking ‘Create one!’ link on the next page.

You also need to have a valid license of Windows 10 to download this tool. Since you are already using Windows 10, it is safe to assume that you have a license.

Another important thing to note is that you must have the correct version of Media Creation Tool for your Windows. There are two versions available for download – 32 bit and 64 bit. You can check the version of the OS in the System Settings in Control Panel (available in Start menu).

Run the tool and you will see the Windows 10 Setup screen. Here are the simple steps to get started:

  1. Select ‘Create installation media for another PC’ and click Next (the other option is ‘Upgrade this PC Now’ in which we are not interested)
  2. On the next Window titles ‘Choose which media to use’, you will get two options and you can pick either:
    1. USB flash drive: Create a bootable flash USB drive, which you can use to reinstall Windows 10. The drive must have at least 3GB space. Creating bootable drive will wipe out all other content from the drive.
    2. ISO file: You can use the ISO image file to reinstall Windows 10. However, you will need to burn this file to a DVD later.

USB flash drive is a straightforward option to create a bootable media for Windows 10 installation. However, if you are okay with burning the ISO file, you can go for the second option as well.

Once you click ‘Next’ after choosing the desired option, the setup will first download Windows 10 and then create Windows 10 media. The entire process may take from few to several minutes depending upon your hardware.

When the media creation process is complete, you can reinstall Windows 10 easily. All you need to do is insert the media (USB drive or DVD) in your computer and restart it. If the right boot priority is set in the BIOS setup, your computer will detect the media and begin the reinstallation process.

You May Need to Edit BIOS Setting

In case your PC restarts to Windows 10 without reinstallation you need to change the boot priority in BIOS. The process may vary slightly depending upon the model or computer brand you own. But, the steps are usually more or less similar.

Restart your computer. When it shuts down and begins to restart, on the first screen that appears, press the key specified on the screen to enter the BIOS setup. You need to be very attentive as the screen appears only for a very short time. If you miss it, you will need to restart the computer again.

Most computers require you to press ‘Del’ or ‘Delete’ key for this purpose. But, it may vary.

When you are inside the BIOS setup, locate the Boot related section and change the Boot priority to the media you wish to use.

Keep the media inserted and exit BIOS. Your computer will restart to the installation menu. Follow the onscreen instructions to complete the installation. The entire process may take several minutes depending on your hardware specs.


It is a good idea to create a bootable media as it can be used for clean installation when you don’t have Windows 10 already installed. But, for those who have the OS already running, using the Reset Function makes more sense as it is simpler and straightforward. Here are the steps:

  1. Click the Start menu
  2. Go to Settings
  3. Select Update & Security
  4. Click Recovery
  5. Select Reset this PC

This will start the installation process instantly. You only need to follow the on-screen instructions to complete reinstallation.
