Hello! I've used MacBook Leopard for about 2?3? years and still clueless about apps. ha. I just bought SP3 Windows XP Professional Version because several of the programs I use for my classes only run on Windows software. I know that I have to download Bootcamp 2.1 before I install any SP3 Windows product, and promptly did so. Can anybody tell me step-by-step instructions on how to install Bootcamp 2.1 and Windows XP SP3 to my Macbook?
