Okay, so I have the black screen with movable mouse error which I have done some research on and found that it is quite common. BUT. All the solutions that I have seen require you to go into the windows startup options by pressing F8 during startup. Whenever I do this however, I just get a disk read error. I also do not have the windows 7 disc because I bought this computer used. Any help would be greatly appreciated I am stumped. Thank you in advance.
