My Gigabyte GA-EP-UD3P refuses to boot to anything but Windows, even without any hard disk connected.The BIOS says: Boot from CD/DVD... and then it boots to a screen saying the Windows hard disk is missing, which I didn't know was even possible. I was previously using Bitlocker w/ TPM on the drive, so I'm not sure if that's related.
I've reset and cleared the CMOS/BIOS, and tried moving the SATA port around for the DVD drive. The USB stick I have the .iso on also won't boot, but I booted from it and installed a system from it on another system just a few minutes prior.
I'm not really sure how to proceed, is there anything I can do that I haven't done yet?
