I know you can use disk management, problem is, ones marked as boot, the other is marked as system (i want to get rid of the system 1) and i cannot fgure out how to make it let you, as it considers both as very important. Vista just lets you delete it. Not sure if that was a delberate design feature though knowing microsoft...
