I recently bought a new ASUS notebook. They are offering a free upgrade of the pre-installed Windows XP version. With this upgrade I woul loose my XP version. Now I would like to keep my XP version as it is now AND have Windows Vista, changeable with a bootmanager. I also have another version of XP and legal OEM number from my last computer (which is broke). I think I could totally legal upgrade my existing XP to Vista and install my old XP afterwards, but I would still like to keep my XP whihc is running now, because it was installed from ASUS with all the driver, nice themes etc. So how can I do this? Is there a possibilty to take an image of my exisiting XP and change the OEM?
