I had to disable Secure Boot and enable Legacy Support to be able to boot a Windows 8.1 64bit DVD from the CD drive in the BIOS menu to install Windows.
Is there any reason why this happens? Is there not a way to keep secure boot enable and boot from the DVD drive? I had no option even when enabled from within the BIOS.
This is a Self burned ISO/DISK if that matters. Never heard of that being an issue before.
