Apple has released a utility to create a Lion recovery partition on a flash or external drive. This makes tools such as Lion DiskMaker obsolete, since Lion can even be installed on a fresh disk using the recovery utility—eliminating the need to first install Snow Leopard on the target machine. The tool is perfect for users who want to start from scratch with minium hassle, or for those with borked machines that need to be repaired.
The Lion Recovery Disk Assistant lets you create Lion Recovery on an external drive that has all of the same capabilities as the built-in Lion Recovery: reinstall Lion, repair the disk using Disk Utility, restore from a Time Machine backup, or browse the web with Safari. This drive can be used in the event you cannot start your computer with the built-in Recovery HD, or you have replaced the hard drive with a new one that does not have Mac OS X installed.
- 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.
