    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?

    You should be able to install to any partition without losing data or needing to repartition. The OS update expected soon (10.6.5) is a straight in-place upgrade.

    OS 10.7 will probably be out in about a year, and again you shouldn't have any problems there either.

    I do it all the time. Ain't nothin' special and the installer won't let you mess up. It gets annoying and tricky when you need to do something like change the size of the Boot camp partition, especially when you're like me and have an encrypted hard drive.

    Yeah don't worry man it's totally fine :) the reason being is because when you partition the computer basically thinks you have two entirely separate hard drives. So the OS update will only affect one side. Don't worry :)
