You need either a Windows installation disc or a system repair disc. If you don't have either you can create a system repair disc on another PC but it has to be on a Win 7. I think it has to be 64-bit too if that's what you have.
The boot priority may already be set to CD/DVD. Try and find out. If it doesn't boot the CD then you need to change that in BIOS. Hopefully you won't have to do that.
