So I have a MacBook 2.0GHz, 80GB, 2GB RAM. I need to run a few Windows applications for work so I thought I would put Windows on my MacBook. I carefully followed the instructions through Boot Camp but when I get to the partition part I get this error message: I still got the error after a second try. After that I just didn't do anything about it. EDIT: ok I read more about it and it said to make sure my start up disk was formatted to Mac OS X Extended (Journaled), however when I look at my start up disk it says Mac OS Extended (Journaled) Any suggestions? I haven't searched a lot, is there a thread about this already?
