ASROCK Extreme6 UEFI Boot Issues

Trying to boot the X86 / X64 image of HA using a PC that has an Asrock Extreme6 motherboard. I don’t see the UEFI boot option when I go to the boot menu, although I’m sure that UEFI is capable of this device. In searching the forums it looks like Asrock boards have this issue, just wondering if I missed something or if anyone has been able to get it to work on an Asrock board…
