Please help me. I'm so upset right now. I dropped by Gateway LT4010u that I've had since December and now it won't work. It says "A disk read error occurred. Press Ctrl Alt Del to restart." Of course when I do that it keeps going back to screen. It doesn't have an option to boot in safe mode. There's no CD-ROM so I can't reinstall Windoes. It only gives me F2 to go to set up and F12 to change boot device (and I don't even know what that means). My laptop has Windows 7 starter kit on it with Intel Atom. I'm not sure if that info even helps. What should I do?! I've seen that it could be the hard drive is loose but I don't know how to get to that either.
