Boot Camp Windows Installation Problem

I have a 1st generation macbook pro running snow leopard 10.6. I've been trying to install windows xp, vista, or 7 using bootcamp but for some odd reason i cannot boot into the cd. I put the cd in and made sure the macbook is reading it (which it is because the icon shows up on the desktop) before i hit "start installation". the laptop would restart but it doesnt boot into the cd, it just goes right into the gray screen and stays there while i hear the cd spinning.

I've installed windows
xp using this method but that was about 4 years ago, for some reason the hard drive died on me so i have to do this whole process over again. I dont recall having this problem either.. any help or suggestions would be greatly appreciated! thank you!

 

i have boot camp opened up and like i said, i make sure the cd is read before i start the installation. i get passed that part, the part im stuck at is right after the macbook reboots its supposed to read the windows cd as if i was reformatting from a pc, but it doesnt, the gray screen comes on and it just stays there.

 

bump..
