What I was saying is that you have to boot from the UEFI DVD to install the OS. No all you have is EFI and not UEFI.
That is why I said to look for a newer board that supports what you want UEFI. There is no bios update so you board looks like that.
EFI is a forum of UEFI, but UEFI is better. This is the only option you have "EFI CD/DVD Boot Option [Auto]"
So if you didn't change that option in the bios you board is already running EFI.
