Boot Camp/Disk Utility Issues

I just upgraded to Leopard. I had parallels installed (I deleted it using appzap after installing Leopard). At any rate, here's the issue:

When I try and install Boot Camp it says the following:

"Disk cannot be partitioned b/c some files can't be moved...

Back up disk and use disk utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp assistant again."

Is there something I can do so I don't have to go through all that?

THANKS A TON

i had a problem similar to yours. i tried everything imaginable including formatting miltiple times and still no luck. a friend sent me this link and it solved all of my problems. the drive has to be partitioned with the guid partition table, not the apple partition table. might give it a try if you cant find any other solutions.
