I am unable to boot up the laptop because of an update. It's not my laptop but I mainly use it. The person who owns the laptop never made backup disk and the laptop didn't even come with any. I can't do anything other then watch a black screen. When I try to do the system recovery, I get a blue screen. When I try to do anything else like safe mode, debugging, etc. I still get a black screen
