So I fell asleep last night with my laptop on my bed, and I guess sometime during the night I knocked it off my bed, and it fell 2-3 feet to the ground landing on its side. I've knocked it off before, but this time it shut it off and when I tried to turn it on it plays a funny beeping melody and says "no internal boot device found - insert disk and press any key". From there I ran some of the diagnostic tests I could fine in the boot up menu and it says I apparently have no hard drive...

Halp, i'm really bad with computers and I need it for school, so using warranty is last resort (if I even have it.)

computer is an hp envy
