I suspect this may be due to a droplet of water getting inside it earlier in the day. Do you think the disk is completely fried or maybe just not connecting properly ? To give context, i already had windows 10 on it. It just randomly booted up to bios with my hard disk gone. P.S: I am not an expert whatsoever
Does yours have the m2 drive or the sata drive?
Either way both aren't in easily accessible place for water to reach them and it's likely you've damaged the motherbd instead so I'm moving this to our Laptop Tech Support section instead.
