I did not want to lose the pre-installed W7 starter and my W7 ent runs out in a few months time use the concurrent login and remote desktop all the time which starter v does not have. The W7 Starter is on a Acer netbook, which should arrive tomorrow. I did not want to interfere with starter. I am quite familar with dual booting a while back as an exersize for my students we installed booted W98 NT W2000 Xp & RedHat 9 on one pc. I just have not tried this before. The W7 Ent will be sort of vLited to 1.3gb .iso runs real quick. As I write how would I save the pre-installed W7 starter so maybe I only install Enterprise but can re-install W7 starter in the future.
