There are various buttons that can get ya into your BIOS, it all depends on the pc/BIOS manufacturer. Normally F1, F2, F10, Delete will do the trick. F8 takes you to your boot menu for safe mode etc
@wally222, Do you know how to navigate around the BIOS? The keys you use are listed at the bottom. Load optimal settings is normally in the far right menu. At least mine is.
