I have an ASRock Z170 Fatality Gaming K6 and somehow while in the BIOS(v1.7) I turned on the boot drive selection menu during startup. I only boot from my C:/ drive so I don't need the menu to come up. At first I had both the C:/ drive and my DVD drive enabled as selections but I managed to turn of the DVD selection but I can't figure out how to stop the menu appearing during boot up. Cheers!
