i dunno how to get rid of that particular error but i would never advise someone to write over the existing os or "upgrade" but do a comeplete format and fresh install. yes u have to back up ur data but its worth for the less headaches u will get since windows gives enough of them as is with the perfect install. if u dont have the means or dont want to back up u could create a new partition for windows alone and install to that partition and can still format and a fresh install without losing data and then u could have a dual boot with 98 and xp. well thats what i would do if i were u.
also u can try running sfc /scannow from the command prompt and windows will verify all the system files altho ive never had this fix a problem but its easy and if it works then great if not then its not a big deal to do
