I installed XP via bootcamp, then heard about Parallels and now I'm running XP virtually. The thing is, I didn't even create enough space to run anything. I need to install a program for school through XP, and I realized I never bothered changing the partition size. So right now I only have 5 GB running on XP. Dumb mistake on my part, but I want to delete the existing partition that's running on bootcamp and reinstall using Parallels. My question is: How do I know I have enough space this time? Where as in bootcamp, you select the partition size as you begin. Any help is much appreciated.
