Hi there, I seem to be rather confused after reading so many websites which say its possible to install windows 7 upgrade over xp by custom install in bootcamp. I purchased a windows 7 upgrade which I have downloaded as a ".img" file. However, bootcamp doesnt recognize my .img disc. I have tried converting the .img to a .iso, and then burning the .iso as a iso disc, but still no luck. (Im not sure if its because of Active iso software Im using to burn the discs or if im doing something wrong.) I have a legit version of XP already running via bootcamp, but I'm really in need of help, please.
