My computer had been working perfectly until now. I carried it in my backpack for a little bit, and when I tried turning it on at home, a black screen came up saying "Operation System Not Found." What's wrong??

I hardly know anything about fixing computers. I obviously didn't meddle with the operating system or whatever. I really don't know what's wrong.

I remember you're supposed to press the F2 key. I did, and a screen came up that's titled "Insyde H2O Setup Utility Bios Version R029Q2." I have no idea what that's about so I didn't do anything else.

I'm using a Sony VAIO laptop with Windows Vista.

Please help!

Chances are your hard drive needs to be reseated in the laptop, or has gone bad entirely. If you are feeling daring you can try going back into BIOS and see if it mentions a "Hard Drive" or "HDD" at all. You can simply use the arrow keys to navigate around though the different tabs and if you see something "Not Found" then let us know. If you see it mention the hard drive then also let us know. You don't have to save any settings at this point.

Thank you! I checked the BIOS and it said "Internal hard disk drive." Then I tried reseating the HD. I just opened the HD compartment in the back and the drive was loose! It wasn't even connected to the little metal things inside the computer. No wonder why I couldn't boot up my computer. I pushed the drive back into its original position and now everything's working fine. Phew, that got solved faster than expected. Thanks again!
