I turned off the Core Storage volume manager on my OS X partition (i.e.
diskutil cs revert). Now my Recovery HD displays in Disk Utility and in Startup Manager.
I don't like this and would like to undo this change. For example, I can no longer boot from the recovery disk by holding Command+R at power on, instead it boots into Internet Recovery Mode.
diskutil cs convert to change it back but I still see the Recovery HD everywhere.
Is there a way to completely restore the disk (and the partition CoreStorage settings, really the entire disk) to factory defaults?
