This unit comes with Windows XP pre-loaded. We will pre-load your MacBook with a 20GB Fat32 partition, pre-loaded with Windows XP Pro with Service Pack 2. (If you would like a different size on the partition, give us a call at 888-563-6112). You also get a licensed copy of Windows XP on CD, and you can reinstall if you need to. Otherwise it is a stock MacBook 1.83Ghz.
For details about running Windows XP on your MacBook or other Intel Mac, see Apple Boot Camp Site.
Remember, Boot Camp is public beta software, and works well, but is does not support all the features of your MacBook Pro under Windows XP. Also, the public beta of Boot Camp will expire when Mac OS X 10.5 Leopard comes out, or Sept. 2007, whichever comes first. You will need to purchase Leopard for continued support. For more information, please check out Apple's Boot Camp FAQ.
We don't support Windows XP - and neither does Apple. We'll install it for you, but, hey, we're Mac people, so we can't help answer Windows questions! Give us a call at 888-563-6112 if you have any questions before you buy. Your use of Boot Camp beta should be for evaluation purposes only and is subject to the terms and conditions of Apple's Boot Camp license agreement.
