I'm trying to partition my hard drive with Boot Camp Assistant, however, each time I attempt to partition, I get this error message:
When I go to Disk Utility, I get this window:
How do I navigate Disk Utility to achieve what I need to do? Do I re-format the drive named "200.05 GB Hitachi", or "Macintosh HD"?
Thanks in advance for all your help!
