Macs released in mid-2011 or later, along with some older Macs once you install a firmware update, include a new feature called OS X Internet Recovery (Lion Internet Recovery under Lion). Alternatively, if you’ve got a wired connection, be sure the Ethernet cable or USB-to-Ethernet adapter is connected to your Mac. If you want to connect to your network or the Internet, and you haven’t already chosen a Wi-Fi network, you can do so using the Wi-Fi menu. Regardless of which method you used to access recovery mode, the menu bar displays OS X’s Input, Wi-Fi, and (on laptops) battery menus. OS X Recovery, also known as recovery mode, offers a number of useful troubleshooting options. (Note that this Utilities screen is the same one you’ll see if you create a bootable Mountain Lion install drive and boot your Mac from it.) After a brief delay, you’ll see the new OS X Utilities screen. Select Recovery HD and then click the upward-pointing arrow below it to boot from Recovery HD. However, you aren’t required to perform this step now, as you’ll also be able to choose a network once you’re booted into recovery mode.

If you’ll want to connect to your local network (for example, to access backups on a Time Capsule) or the Internet in recovery mode (see “Using recovery mode,” below), you can use the pop-up menu at the bottom of the screen to choose a local Wi-Fi network provide the network’s password when prompted. One of the volumes will be called Recovery HD. Restart or start up your Mac while holding down the Option key keep holding Option until the Startup Manager-a gray screen showing all connected, bootable volumes-appears. Hold Option at startup, and you can choose to boot from the new Recovery HD volume. The alternate way On any Mac, you can access recovery mode using OS X’s Startup Manager: If you ever needed recovery mode, you can boot into it using that external drive or thumb drive. If you were using Boot Camp, you’d then use Boot Camp Assistant to set up Boot Camp again, and then restore your Boot Camp data.Īlternatively, you could install Mountain Lion on an external hard drive or thumb drive, which would create a usable Recovery HD partition on that drive.

Your only option, according to Apple, is to back up your drive (including your Boot Camp partition, if you have one), erase it (repartitioning it as a single-partition, Mac OS Extended volume in the process), reinstall Mountain Lion or Lion, and then restore your data from your backup.
Unfortunately, if you didn’t already have a Recovery HD partition from a previous Lion installation, and the Mountain Lion installer can’t create the partition, you can’t add it later. So not everyone will get this useful feature. In addition, if your drive has a non-standard partition scheme-for example, if it’s part of a RAID, or if you partitioned the drive using Boot Camp Assistant and then tweaked the drive’s partitions later-the installer won’t be able to create Recovery HD. For starters, as Apple explains, the drive must be formatted with a GUID partition scheme and Mac OS Extended (Journaled) format, and it must be at least 13GB in size.
(If the drive was previously running Lion and already has a Recovery HD partition, the Mountain Lion installer simply updates the partition’s contents.) I say “attempts” because the installer is not always successful. When you install Mountain Lion on a drive, the installer automatically attempts to repartition that drive to create the invisible Recovery HD partition. Why you might not have a Recovery HD partition Separate from-but closely related to-OS X Recovery is a feature called Internet Recovery, which provides similar features even if your Mac’s drive is damaged or has been replaced.
