Ok, just updated my bios which caused a **** storm, but anyways, 750i FTW, 2 WD hard drives that were working fine before. now after update, windows wouldnt boot. Tried everything but I kept getting a 75 mobo error which is an IDE error and I have nothing hooked up via IDE. So i unplugged my 2nd HD and booted no problem. Hooked it back up got an error. Ive tried 3 different drives to no avail. Any ideas why this would not be letting me boot into windows?
