windows 7 bootcamp install problem

I've installed windows XP on my MacBook Pro with no problem but I am having a problem trying to install windows 7. I have Snow Leopard running on my MacBook and am using bootcamp to install windows 7. When I get to the part where I put the windows 7 install CD in the drive and hit install, I get the following text displayed on the screen:

1.

2.
Select CD-ROM Boot Type: _

I never saw that before but more importantly, I can't even answer the question because it doesn't seem to recognize my keyboard. it's like I have no keyboard. I get no response at all no matter what keys I press. It's like frozen.

Has anyone seen this before?
