Just built a new PC today and used the AsRock Z77 Motherboard. I haven't built a new PC in a long time, probably XP days. Went to install Windows 8.1 from a USB disk and Windows is telling me it cannot find my hard drives, even though they are listed in the BIOS.
I am using a SSD Samsung 850 EVO SATA drive with default BIOS settings. Any help at this point? I have tried my USB disk in all USB ports and tried Win7, still the same result.
