Question Bios update failed?

[Strongwolf2]

I just updated the bios on my ASUS Prime B-350 Plus. I haven't been able to boot it up since. I don't understand what happen. Is there a way to reverse the operation. There was nothing wrong with the board before the up date, just sometimes it has problems recognizing the M.2 drive.
