Windows Bootcamp problem.........

Ok the probelem is simple to explain. I downloaded Bootcamp and did all of the hard drive partitions and all of that good stuff and when I start the Windows install thats when I run into my problem........ And the problem is that the keyboard on my Macbook stops working. At the windows install screen where it states press enter to install, press r to repair and f3 to quit the keyboard does nothing. I press enter and nothing, I press f3 and nothing. I have to restart the computer and hold down the mouse button so that I can get the Windows intall disk out. Yes the Windows is XP Service pack 2 so I don't think thats the probelm. Any help would be great!
