If you don't have recovery HD or if that has been deleted for any reason: Nice article above and reminds me to create an image of recovery partition as well as a backup. If your Mac doesn't have a recovery partition, Carbon Copy Cloner recommends reinstalling OS X: (This has the additional benefit of updating the recovery partition with the most recent data, too.)Ĭarbon Copy Cloner has an option to add a recovery partition, but it needs to copy the recovery partition from another disk or a backup archive. Reinstalling OS X is also recommended by SuperDuper's developer:Īctually, you can easily recreate the recovery partition by simply reinstalling Lion from the App Store. Upgrading to a new major version of OS X will also add a missing recovery partition. Apple should call it something less scary like "repairing OS X", because it is the solution to a lot of issues like this, and it is not such a drastic operation especially if you have backups. Reinstalling OS X over an existing installation is similar to upgrading to a new major version of OS X, or it keeps user files and settings in place but replaces system files with new versions. It took about two hours, and after that I had a working recovery partition again.

First I removed the Recovery HD partition. If you reinstall OS X from App Store, it also recreates a recovery partition. As many have pointed out, it appears that the recovery contents are not universal and instead customized for the specific hardware, so recreating it from the official tools is much preferred unless you wish to test well and are saving time by automating tens or hundreds of macs and can control for hardware differences in your process. I don't know if you can move a Recovery HD around like a normal partition or need the other defaults write command to roll your own recovery HD, running the Lion installer a second time was fine for my needs. defaults write DUDebugMenuEnabled -bool true.I only needed to turn on/off the one command: pointed out these hidden commands from this MacWorld article. The debug menu looks as follows - selecting show every partition will let you see whether your Recovery HD is on your drive. mac:~ mike$ diskutil listĢ: Apple_HFS Macintosh HD 999.3 GB disk0s2 You can use the diskutil list to see the Recovery HD if you don't mind terminal.app commands. Disk Utility hides the Recovery HD (and other partitions by default) unless you enable a debug menu. It took a good 35 minutes to run the installer again. Hold the option key while selecting Purchased.Start the App store and pick any view except Purchased.To get the Installer (since we didn't save it and it deletes itself on running the first time). Re-running the Lion installer will create a workable recovery partition. Just as a backup copy of a good file needs to be made before the file comes upon it's demise, this tool will not help if you start with a partition that is missing or broken. The Lion Recovery Disk Assistant lets you create Lion Recovery on an external drive that has the same capabilities and limitations as the built-in Lion Recovery. The Lion Recovery Disk Assistant can make a backup copy of the recovery partition. Rerunning the Installer works for OS X 10.7, 10.8 and 10.9 - running the recovery disk assistant isn't a good idea if you are running 10.8 or newer OS as well as hardware that ships with newer builds of OS.
