HI There,

Unless someone has gone into what is called your BIOS and disabled your hard drive as a recognizable device, your message most likely means that the WIndows System on it is corrupted enough (maybe virus) that the "boot sector" of that system can't be seen by the computer and it could also mean that your hard drive is ruined.

This isn't a problem you can just find a quick fix for. My first concern, if I were you, would be important data you needed to retrieve. In that case you would hope that someone can put your hard drive in an external enclosure, and just get the data files off it.

If you have a Recovery Disc of any kind for your Compaq, you could insert it and start from that disk and it might repair and restore the files that are needed to see the Windows system and start the laptop again.

It's very hard to say exactly from a distance with what you've told us.

Best Regards,

My Compaq Presario F700 dropped approximately 2 feet to the floor from on top of a suitcase at the airport. It was in a case, but not a thickly padded one. When I tried to use the laptop after the fall,...

Try reseating the hard drive and the RAM modules, the fall may have slightly loosen these components.
The error message "Operating System not found" means the laptop could not find the hard disk, this problem could be the hard drive needs reseating, a faulty hard drive (they don't like being dropped), or a faulty disk controller.

Operating system not found

Is the hard drive being recognised. IF it is then if you format and reinstall the operating system that will fix the problem. Sometimes it's possible to repair the OP instead of doing a full format and reinstall but I rarely find that successful.

Good luck

Compaq presario not working

This generally indicates hard drive failure. Try reinstalling your operating system, if you have any problems during or after the install, then the hard drive will need to be replaced.
