Main osx 10.6.8 Partitioned osx 10.7 just to mess around with Lion OS (everything went smooth). Now that i'm done with messing around with Lion OS. I want to remove the Lion OS partition. In disk utility (under 10.6.8 boot), i have highlighted the Lion OS partition and clicked the (-) sign. Disk Utility does its thing and came back with an error. (Partition failed: This operation requires a newer version of Mac OS X for this disc). I do have the latest osx 10.6.8. I have tried this twice, failed. Rebooted and tried again..still failed. What gives? Can anyone help me? Thx.
