Welcome to the Apple Support Communities
On OS X Mountain Lion, Boot Camp only supports Windows 7, so you can't install Windows Vista or XP, and if you install Windows Vista or XP, you won't be able to install Boot Camp drivers because they aren't supported under XP and Vista.
If your Mac came with DVDs, insert the Mac OS X DVD (or the Snow Leopard DVD) that came with the computer and install Boot Camp drivers. If your Mac didn't come with DVDs, you can't get Boot Camp drivers for Vista
