I would have thought that if you opened C: you would have \program files and \WINDOWS folders, plus \Docs n Setts, [as well as others....]. These are the ones u use as your OS. So open H:\ and just delete H:\Windows [it won't fit in the bin..] and H:\Program Files folders. Check thru docs for files that you may wish to keep. I wouldn let Norton do anything.. If you are concerned post a pic of your explorer window with a bit of tree expansion...C:\ and H:\ .Or two pics...

well, there was no backup or undo for the second OS. i went ahead and deleted the all the folders in H: and then edited the boot loader (removing the last line). i restarted without any problems and the second XP option (2nd partition) was no longer available as a selection. thanks guys!!
