In this step by step tutorial we will tell how to do a clean installation of Windows 10 using Bootable USB Drive or DVD. The pre-requisite is obviously that you have created a Bootable USB Drive already and you can read our tutorial to learn how to do it.

If you want to perform a clean install on your PC, or if your PC doesn’t have an operating system, you can use the Bootable USB / DVD. Keep in mind that, if you format a drive partition during installation, any data on the partition will be erased. Be sure to back up any data you want to keep before you begin.

Step 1): Turn on your PC, insert the DVD or USB flash drive, and then shut down your PC.

Step 2): Restart your PC, and then press any key to boot from the DVD or USB flash drive.

Step 3): If you restart your PC and your current version of Windows starts, you might have to open a boot menu or change the boot order in your PC’s BIOS or UEFI settings so that your PC boots from the media. To open a boot menu or change the boot order, you’ll typically need to press a combination of keys (such as F2, F12, Delete, or Esc) immediately after you turn on your PC. For instructions on changing the boot order for your PC, check the documentation that came with your PC or go to the manufacturer’s website.
