Windows Installation

Troubleshooting

Windows installer complains that it can't install from or on a particular drive

Possible cause

The Windows installer can't boot from EFI/UEFI drives.

Solution

Look at the boot order in the BIOS. The primary boot drive should not start with UEFI or EFI. If the USB drive starts with UEFI, the installation files must be copied to a drive (SATA) that does not start with UEFI and the installer must be booted off that drive.
