I am working my way through this procedure using Boot Camp Assistant. I'm in Step 1 where I create a partition for Windows XP and have got a message that "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." I have never partitioned my MacBook Pro. My disk is backed up by Time Machine/Time Capsule so I have launched "Disk Utility". I'm uncertain how to use Disk Utility. Do I erase first, then partition, or does partitioning simultaneously erase? If anyone has gone through this experience, I'd appreciate any hints/advice on what to watch for.
