Parralles 4 vist boocamp

Hello,

new here and have a question on running a vista boocamp partition and parallels 4 together.

I have a vista boocamp partition up and running. I want to use this install for both bootcamp and parallels. I know parallels can use it, but will the two play nice together? Im not looking to migrate, I want to be able to use either. When Im inosx I want to sue my vista install from bootcamp, but I also want to be able to sue bootcamp native also.
