I get the Operating System not found when I try to boot up. Everyonce in a while it works fine. Prior to getting this error (the last time it worked) I rcvd a DVD not found error. Any ideas? Could it be just replacing the DVD player?
This THREAD helped me when I was having boot issues. Good Luck.
It’s possible the hard drive is failing. Try reconnecting the hard drive first. If it doesn’t help, try replacing the hard drive. HP Pavilion dv9000 laptop. Removing hard drive, memory, wireless card, keyboard.
