I have installed Mavericks on a separate partition along with ML and Windows via boot camp. After happily poking at a few iterations of the beta releases of Mavericks, I want to remove the Mavericks partition, which currently boots as the primary partition. How do I 1) Delete the Mavericks partition. 2) Revert ML as the main OS while boot up. 3) Merge the Mavericks Partition back to ML... don't want extra partition. 4) Ensure I end up with ML and boot camp, that I don't end up with a MBP that does not boot up. P.S I will have things backed up just in case.. Thanks, hope others are in the same boat and can help me/others out.
