A couple of years ago, I installed the Boot Camp beta on OS X, reserved 20 GB for Windows XP, and installed an XP in that partition. Since then, the Boot Camp beta expired and I used Parallels to run the XP in a VM from that partition. Now I want that 20 GB back.
I'm not terribly worried about the contents of the XP installation on that partition (I can just back up the data elsewhere), but if I can preserve it in a VM that would be a bonus. I would like to remove that partition and resize the OS X partition to occupy the full drive.
What's the proper way to do this?
