Someone in my household dropped their laptop while it was on. It dropped screen down, bottom up. We tried to turn it back on and it went op a screen saying Boot Device Not Found. So it turns on, but does not boot up to the hard drive. I used an Ubuntu Live USB Drive to see if I could read the hard drive and sadly, I can't. There is also a low beeping noise coming from the hard drive. I reseated the hard drive and the memory. Please help.
