Clean Installing Windows 11

This wipes all data from the machine

Please make sure to disable CSM, enable Secure Boot and enable TPM prior to installation of Windows 11.

  1. Create a bootable USB flash drive using the Media Creation Tool from Microsoft. This will also wipe any data stored on the USB flash drive.

It is best to disconnect all storage disks except from the main (C Drive) disk from the computer before installing Windows 11.

  1. Boot into your USB that has the Windows 11 Media on it.

    • You can do this by entering your systems' BIOS and change the BIOS boot order to have USB media as the first priority (this can usually be found under the boot tab), or simply look for the words "boot menu" when you see your BIOS boot screen, press the corresponding function key and choose the USB flash drive to boot from it.
  2. Follow the steps on screen to install Windows 11.

  1. Click Install now
