Your storage device must have at least 13 GB available (after formatting) to install Lion and an Internet Restore partition.

This procedure will install a version of the OS X Lion that is compatible with the Mac it was created with. Using this Lion system with a different kind of Mac may produce unpredictable results.

The OS X installer will not allow an install on a volume that contains a Time Machine backup.

service.info.apple.com/service_training/en/063/en/Lion_InstallationRecovery/index.php?page=printer 5/17 3/25/12 service.info.apple.com/service_training/en/063/en/Lion_InstallationRecovery/index.php?page=printer

Lion Recovery OS X Lion installation begins. Times will vary.

Lion Recovery allows you to repair disks or reinstall OS X Lion without the need for a physical install disc. Recovery is built into your Mac.

When OS X Lion is installed, it creates a special partition on your computer's hard drive called "Recovery HD". This hidden partition includes all of the tools you need to reinstall Lion, repair your disk, and even restore from a Time Machine backup.

Recovery Partition is Hidden

It will not mount on the desktop or appear in Disk Utility.

Successful installation is confirmed. The Mac will automatically restart.

New Mac Computers: Restore Discs Not Included

Computers that ship with Mac OS X 10.7 (Lion) do not include restore discs or flash drives.

Recovery HD

Hold down Command-R during startup to boot into the Recovery HD, or hold down the Option key to access the Startup Manager. Select Recovery HD.

A "Mac OS X Utilities" application window should appear after the Recovery HD is finished starting up.

If OS X Lion was installed onto a new disk or partition (that does not have any version of Can'tOS X already access installed) Recovery you will HD? see setup screens. Otherwise, you will encounter the login screen or desktop (based on your Users & Groups system preference). If you used Command-R to start from Recovery HD and you see a login window or your own desktop and icons, it is possible that you didn't hold Command-R early enough. Restart and try again.

If a firmware password has been enabled, do not use the Startup Manager as Recovery HD will not appear. Instead, hold down Command-R at startup and enter the firmware password to access Recovery HD.

When FileVault 2 is enabled, Recovery HD will not appear in the Startup Manager. Instead, hold down Command-R at startup.

2. Broadband access to the Internet DHCP Enabled; WPA/WPA2 Wi-Fi or Ethernet network connection.

3. Apple ID and password If you OS X Lion was purchased from the Mac App Store. When the Mac determines Recovery HD is unavailable, it starts Internet Recovery.

Older Mac Computers

If you can't startup from the recovery partition or Apple's servers via Internet Recovery, consider the following options: service.info.apple.com/service_training/en/063/en/Lion_InstallationRecovery/index.php?page=printer 7/17 3/25/12 service.info.apple.com/service_training/en/063/en/Lion_InstallationRecovery/index.php?page=printer options:

1. Startup from an external storage device that has OS X Lion installed. 2. Startup from an OS X Lion USB thumb drive. 3. Startup from a Snow Leopard install or restore disc.

Note: Snow Leopard (or older) repair tools and utilities may not work with OS X Lion.

External Recovery Disk

You can also create Lion Recovery on an external hard drive or USB thumb drive that has all of the same capabilities as the built-in Lion Recovery. The drive must have at least 1GB of free space.

The Lion Recovery Disk Assistant will erase all data on the external drive when creating the Recovery HD. You should either backup your data before running the Lion Recovery Disk Assistant, or create a Select your preferred Wi-Fi network. Not applicable to wired network connections. new partition on the external drive. Note: Network must be DHCP enabled. Only WPA/WPA2 Wi-Fi networks are supported.

Important Points

In order to create an external Lion Recovery using the Lion Recovery Assistant, the Mac must have an existing Recovery HD.

If the computer shipped with Lion, the external recovery drive can only be used with the system that created it.

If the system was upgraded from Mac OS X v10.6 Snow Leopard to Lion, the external recovery drive can be used with other systems that were upgraded from Snow Leopard to Lion.
