I have a hp pavilon. It had win me but i was upgrading to xp pro and in the middle of installation there was a fatal error. I can't go back to win me or anything. I download a different version of winxp pro and the same error occurs. i download a different version of pro and the error still occurs. note that i'm in the middle of installation and i have no recovery disk for it. what should i do to get back to a windows or complete the winxp installation?
