hi, I just went thru the hassle of boot camping my mb pro and adding windows 7 ultimate. Man windows is a horrid operating system. From Boot Camp i couldnt start from the windows installer so i thought to go from windows xp pro to windows 7. Install went smooth but i couldnt install any of the service packs you need to upgrade to windows 7. I couldnt get the drivers working even though i have the snow leopard install disk with the windows drivers on them. I was able to get my network drivers going. SO i connected to windows update and upon downloading the service packs. I get a error message saying service packs and updates cannot be installed. After six hours of dealing with this . I just deleted the windows partition. I will only deal with windows bs at work.. sheesh..
