I have been trying to restore the operating system from the hidden partition. I can access the D: drive, there are a lot of files there. At startup I held down the f10 key to initiate system restore when the logo screen appeared. No recovery screen. Then I tapped the key repeatedly while the logo screen was up, then from the time I hit the power key, every varation I could think of. Is there anyway to initiate Windows setup on the restore partition from a cmd prompt, a XP floppy startup disk or some other aproach. I'm perplexed. The HP web site was no help to me. This is a Pavilion Desktop from 2002.
