Starter to Home Premium ? Just purchased an HP Mini 110 last week , and they have added an option to add Windows 7 (Starter) as an OS. My question is; I have downloaded W7 Home Premium(Retail) and its on a flash drive. Would I be able to easily upgrade Starter to that? If so how? Just run the setup file? Or will it cause problems( like make me lose everything, no wifi, etc...)?
