All articles about biosinfo reference that either your recovery disc has a bad biosinfo file, or your computers biosinfo file is corrupt, or... the biosinfo file doesn't match between your computer and the recovery disc... meaning your disc thinks it doesn't belong to the computer it's trying to recover. I have searched long and hard through Google groups and I cannot find a resolution... given that you have no option to cancel the windows xp setup.
I guess I should have asked you whether you're using a full version XP disc to attempt recovery, or is it a Dell recovery disc. I assumed it was a Dell disc, since you said you have a Dell PC. There may be something we can try if it's a full Xp disc... but if it's a Dell, then I honestly don't know where to go from here.
