You Can't Be Serious

MacBook Pro 10.6.1

I needed certain USB HW/SW that would not run under OS X so I decided to install a Bootcamp partition and then Windows XP Pro.

I have 121 GB available on my MBP drive

I ran the Boot Camp Assistant and got the following message:

"The disk cannot be partitioned because some files cannot be moved.

Back up the 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."

Are you kidding me with "some files cannot be moved."

I run a clean system, a very clean system - what files can not be moved? - they are all your (Apple) files - this is the worst "error" message I have ever seen.

Any idea of what this means? or how to install Bootcamp?

Thank you.
