I recently purchased a MacBook Pro and plan to partition the hard drive so that I can run both Mac OS and Windows 7. Assuming the rumors are true, Apple may be releasing a newer version of Mac OS X in the upcoming months. I am wondering whether it is fairly straight forward to upgrade the Mac OS on a MacBook with a partitioned hard drive, or whether I would have to repartition the hard drive afterward and reinstall software, data files, etc. I understand there is WinClone and SuperDuper! available for backing up Windows and Mac OS, so I can do this in advance. However, I was just wondering if anyone out there has had experience upgrading the Mac OS on a computer with a partitioned drive. If so, how did you do the upgrade? Any suggestions?
