Hi All, Was trying to set up a Windows XP SP2 partition, which I had set at 32GB. Here is the message that I got... 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. Does this mean that I need to back my system up, and then reformat the entire HD?? I tried Virtual Box, and do not like the VM set up. Prefer the full resources of the machine running Windows. Thanks for all the help.
