If there are important things on that hard drive - don't formatt! I had this error on my old
Texas Instrumants laptop
- untill I smashed it to bits
with a hammer... but that's beside the point! :) I believe it [Operating System is not found] means the hard drive is not recognized. You can check in BIOS
(it should prompt
you to enter bios/setup when you first turn it on - like hit
f12 or something). There it will tell you if it has a hard drive and much more. The hard drive may be dead. I'd take it to a computer pro. If it's dead, they'll probably charge you about a thousand dollars to remove your important data (happened to me). But don't throw it out - keep looking. Always, Always, ALWAYS back up!!!
