HP doesn't list a fix for this error, HP Support Page
One of the things that can cause this error...bad hard drive. I would expect the worst.
I would try to run the chkdsk /r command from the XP Recovery Console. The link posted by Budapest is the standard reference
for this error...I myself have never found any of these attempted methods to work (I did clean install).

I don't know what disk you are using in your efforts...but it doesn't sound like it's a MS Genuine XP CD.

The problem...is that either your registry is damaged and the system is unable to boot...or something worse (hard drive) is making Windows think that the registry is damaged.
The only known fixes for the error message that I'm aware of...have all been listed in this thread.
