Hi, this morning I turned on my computer and got this screen. Nothing has been disconnected despite what it says, and the keyboard doesn't work. I can't press F8 for more boot option and I can't press Enter to retry the boot. I just don't know what to do. Any ideas? Edit: I tried to get to my boot screen, to boot from the Windows 8 disc and try a repair or maybe a system restore, but either my keyboard doesn't work (I've tried another just in case) or it's not registering the key press.
