If this is a 300MHz PII, I hope you can upgrade the memory to more than 128Meg, otherwise it will crawl. I also hope you upgraded the HDD (~4Gig ?) as XP will fill it as soon as installed. Speaking of which, everybody would rather advise a clean install over an upgrade. If applicable, take a backup, clean your disk, schrink your partition (with gparted or Ranish for instance) and make a 2nd one, then you can apply the "multi-partition install", which I've never done myself so my advise will stop here .
