Do you have Win 7 already on your machine under Boot Camp?
If yes, then just install Parallels - it will detect the BC partition and offer to create a virtual machine from it.
If no, then do you need to access your hardware natively under Windows (i.e., the graphics adapter for hard core gaming or video editing, 3D rendering, etc.)? If all you are doing is running productivity applications, you may not need Boot Camp.
If you don't need the native hardware access (and most users do not), then first install Parallels - it will then prompt you to use the Win7 disk to create a virtual win7 machine under Parallels.
either way, you only need to use the Win7 disk once.
Hope this helps but your original post was unclear about what you have and what you need.
