A clean installation of Windows 11 refers to the process of completely wiping your computer’s existing operating system and replacing it with a fresh copy of Windows 11. This type of installation is highly recommended when upgrading from an older version of Windows or if you’re experiencing issues with your current system.

  3. Locate the “Boot” or “Boot Order” menu and change the settings to prioritize booting from the USB drive.
