Unable to use bootcamp in Parallels 7

Hi, I previously had a bootcamp partition with Windows 7 that I also used in Parallels 7.
In order to install Windows 8 I deleted this partition in bootcamp, as well as the VM in Parallels, and installed Windows 8 in a new bootcamp partition.

Now in Parallells 7 I cannot see the option to use my bootcamp partition as a new VM.
Is Parallels 7 just awaiting an update, or is there something else I need to do to get it to work?
