Ok so I have the Windows XP "back-up" disc that came with my Dell. Does anyone know if it is possible to install windows xp on an intel mbp through this disc. It says that in order to complete installation you have to type in your computer serial number which I have. I just want to know if the disc would be custom made for just that Dell or if as long as I have the serial number it could be installed on a mbp. Thanks in advance.
