Awhile back I replaced my Asrock z77 pro3 with a z77 extreme4. When I did so, it selected my partition of windows 8 to boot from my HDD, which is not installed, so I went into the UEFI to set it to my SSD with installed Windows 8.1 but it doesn't come up as an option, but when I don't select an auto boot option and go to custom boot f11, the SSD is there. So it recognizes it and knows it's there but it won't let me select it for the default boot drive. Ideas?
