We got a new MacBook Pro 15″ at work. I have been trying to install Windows XP SP3 on it with Boot Camp and was having some annoying problems with driver support. I’d do the Boot Camp Assistant stuff in Mac OS X (partitioning the hard drive), restart and install XP SP3 from its CD (taking care to format the Boot Camp partition in the Windows installer!), restart, put the Mac OS X Leopard retail DVD in the drive, run the Boot Camp Drivers Installer, restart, and nothing would happen. No hardware support for anything (not wireless, not the display, not sound, zip).
I reinstalled Windows once and reinstalled the Boot Camp drivers a bunch of times from the retail DVD. Nothing.
Somewhere on the internet just now (I can’t remember where, unfortunately), a single sentence fixed it. “Use the install DVD that came with the computer.” I uninstalled all Boot Camp stuff from the Retail DVD, popped in the DVD that came with the MacBook Pro, and magically, everything is working.
