Hey guys.. I've installed bootcamp before so I dont know why its not working this time. I freed up 70 GB's of space I'm currently trying to place the partition with 45GB on Mac OS and 25GB for the windows XP. I made sure I had no large files left on my Mac OS (I know that the partition can fail when you have large files left (800mb +) I booted from the CD....repaired permissions and repaired the Disk (three times now) made sure I had all the updates...and just installed mac firmware 1.3. I've tried partitioning it atleast....14 times now..and it keeps failing. The best I got was that it installed the partition right to about 90% of the install bar, then died on me (very frustrating). Now it wont work at all. I really dont want to format the Drive, and I dont know how to do it anyway. I know there are hundreds of posts on this, but I've done every single suggestion given in every one to no avail. any thoughts?...thanks Oh, btw, the error is the --can not move files-- one. EDIT: 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.
