One other option for you would be to remove the Windows 7 System Reserved partition. Then it would be a simple task that could be done with Disk Management.
I don't know if you would want to go to that extent. I would read up on the pros and cons first. But if you are game, see here: System Reserved Partition - Delete
I'm still holding out to see what others say about free Partition Wizard. I only tried it that once. There is always the possibility that I am just a "person of diminished intellectual capabilities".
Do you recall what the message was that PW gives you when you attempt to perform the procedure?
