Win 7 reinstall

I am trying to install Win 7 Home Premium on a different HD, I have the original install disks, I boot from the DVD drive and the files load as usual but after selecting language I get the message: A required CD/DVD drive device driver is missing. How do I resolve this? And also is there any advantage to installing 64 bit, my processor does support it.

Thanks, Bob

May be have problem from cd
