At last, I have found a product that will allow me to install a single instance of an OS, and copy it to multiple plartitions, and allow me to boot into any of them... much like the rather expensive HYPEROS (www.hyperos2002.com). Why, you may ask... simple... I now have four XP systems, each of which I can customise/optimise... one for internet, one for games, one for work... all of which was achieved in about 15 mins after installing XP only once! Great Product!!!
