Go back and change it back tot he way it was. During POST You actually need to press the F-key that corresponds to "select boot device" and then select the dvd or flash drive. If you have a graphical bios, you would select the "UEFI:" version of you dvd or flash drive listing. ie- UEFI:8GB CRUZER or it might say UEFI:Windows8.1 instead since it what it says is bios dependant but it will definitly say UEFI in front.
