Windows 8 + UEFI BIOS, “UEFI Firmware Settings” Missing

biosbootuefiwindows 8

Originally installed Windows 8 (non-UEFI install) with a GA-Z68MA-D2H-B3 motherboard.

After upgrading the BIOS to a UEFI version and enabling some fast-boot settings and Windows 8 integration, the system boots to the OS extremely fast. However, I found that the "UEFI Firmware Settings" option is missing from the Windows advanced startup options. Also note, boot loader path is \Windows\system32\winload.exe.

Is there a method that allows for changing/enabling the UEFI Firmware Settings menu entry?

I'm even willing to reinstall the OS, though I also can't seem to boot from CD/DVD at this point.

If you're currently booting in BIOS/CSM/legacy mode, you can convert to an EFI/UEFI-mode boot by installing a suitable EFI-mode boot loader. This process is described here, but be aware that this page is geared toward using DUET on a BIOS-based computer; on a system that supports EFI, you don't need to install DUET, so you can ignore the DUET information on that page.
