So, in my infinite wisdom, while my keyboard and mouse was still functioning fine in bios, but not in windows, I disabled the onboard usb controller driver on my MSI motherboard IN bios and now I can no longer even acess bios when I boot up my system, this is a new motherboard, processor and RAM that I have, and windows managed to install one driver, no idea which, but it was something. I have win7 boot disc and a win10 boot USB but I can't boot to either because I can't get to bios anymore, I also have an MSI driver disc, but my win7 asks before running anything external, and I don't have any way of giving the thumbs up to my PC, what should I do?
