Hi ! This is my first message here. I bought a X201 with a win7 pro sticker (with licence #). I would like to reinstall it, it currently runs a 32bit win7 ultimate (strange ? the sticker says pro). I'd like to install a 64 bit pro version on it. I also bought a x200s. This one has a vista sticker, and is currently running Linux. I think I can reinstall win7 on my x201 as this system has a licence for it. What about the x200s ? Will the vista key work also for win7 ? What installation media should I get ? i don't have any and would like to avoid Lenovo specific medias, I would prefer a vanilla windows.
