There is no way of getting the data back. So I highly recommend backing up any files before continuing with this guide.

How to perform a clean install of Windows 10 Guide

Assuming you already have a copy of Windows 10 either on a USB stick or DVD. Pop it into the computer and restart it. If you haven’t, you can follow this guide on how to create a Windows 10 Installation media.

You will need to create the Windows 10 installation media first, before you can perform a clean install of Windows 10.

Once the computer boots up, you will need to boot into Bios (Usually ‘Delete’, F2, F8 or F10) depending on the manufacturer. Navigate to boot settings in bios and make sure the first boot device is the Windows 10 media, when done, select save and exit.

You will see the computer boot up again, and depending if you have a previous installation already or installing a new hard drive, it will either ask you to press a key to continue the boot or it will boot straight into the installation as it can’t find any OS on the new hard drive.

Eventually you will see a screen like the one below.

Step 1.

Depending on how many hard drives you have in your pc, the Windows setup will list all available hard drives it can access on this screen. If you have Windows installed already, it will say something similar to ‘Drive 0 Partition 2; Windows 7’, this is the drive we want to reinstall Windows to, so what we need to do is to delete all partitions on the ‘Drive 0’ and to do this, select a partition on Drive 0 and then select ‘Drive options (advanced)’ and select ‘Delete’. Continue this on all partitions associated with the drive number, and you should be left with something like the image below.
