When I booted my PC this morning (as usual) it displayed a message saying that I needed to insert a boot device. My SSD was still plugged in. Upon seeing this message I decided to switch to my secondary BIOS, and the PC booted as normal (just without all of my OC settings). Is my primary BIOS spent or is there a way to fix this? My OC wasn't huge (3.4GHz to 4.0GHz), and I'm running a 4670k on a Gigabyte Sniper Z87 board. Cheers for any help.
