I Reset my window xp home edition running system after a serious virus problem which shut my pc down. But me being me i didn't format the hard drive before putting it on again so i have the old system and the new one. The old one is not full and the new one does work but when I boot the pc i get 2 choice of which system to run the old or the new the new works fine and the old is empty. Can i delete this? Also all my program files and settings remain from the old running system can i get rid f these or will i have to re buy windows and reset it again? Many thanks in advance Chris
