OS X Lion or Mountain Lion
A Mac running OS X with an existing Recovery HD
An external USB hard drive or thumb drive with at least 1GB of free space

Built right into OS X, OS X Recovery lets you repair disks or reinstall OS X without the need for a physical disc.
The OS X Recovery Disk Assistant lets you create OS X Recovery on an external drive that has all of the same capabilities as the built-in OS X Recovery: reinstall Lion or Mountain Lion, repair the disk using Disk Utility, restore from a Time Machine backup, or browse the web with Safari.
Note
: In order to create an external OS X Recovery using the OS X Recovery Assistant, the Mac must have an existing Recovery HD.
To create an external OS X Recovery, download the OS X Recovery Disk Assistant application. Insert an external drive, launch the OS X Recovery Disk Assistant, select the drive where you would like to install, and follow the on screen instructions.
When the OS X Recovery Disk Assistant completes, the new partition will not be visible in the Finder or Disk Utility. To access OS X Recovery, reboot the computer while holding the Option key. Select Recovery HD from the Startup Manager.
