I need to install Windows 10 Enterprise in UEFI mode on a Dell OptiPlex 7020 desktop (BIOS version A08).
However in UEFI BIOS mode, I can only boot from the local SSD drive. In the BIOS settings, when I click "add boot option" I only have once choic, that's the SSD drive entry.
So how can I add USB as a UEFI boot option?
I use RUFUS to create a Win10 bootable USB drive.
