I am trying to get my 2002 HP desktop to factory settings in order to give away. I've tried F10 multiple times (tried pushing the button multiple times & tried pressing only once) but no luck in getting the recovery page. I also tried F8 which does not show the "repair your computer" option. Help!
Sorry, but with a 15-year old PC, presuming it has the original hard drive, it's likely that the filesystem has become corrupted over time, and if that has affected the original Recovery partition, the HP reset function simply will not work anymore.
An added problem is that HP stopped carrying XP Recovery Media long ago, so you won't be able to order recovery disks from HP.
