I can't get Windows to fully setup when I try to boot camp

I trying to boot camp my mac with windows. I'm pretty sure I'm doing everything right but if I'm not this is what I'm doing

1. opening bootcamp and entering the windows 7 CD and partitioning the drive.

2. after windows installs the computer restarts onto the windows set up.

3. I sellect the country and all then format the boot camp drive and choose it then hit next

4. the set up does all of the things exept for the last one then it restarts and finishes that.

5. it then starts and goes to the windows start screen (the logo) then the screen goes black. The computer is till on but wont go on to the rest of the set up

This is what I do and what is happening if anyone can tell me what I'm doing wrong or why I cant finish the setup, please do. Than you!
