After downloading the utility,
* Plug anextwernal harddrive or USB flash drive into your Mac.
* Launch Recovery Disk Assistant and select the drive.
* Wait for some time to copy the recovery HD data over to the disk.
Boot from the Lion Recovery Disk:
In order to boot from the external Lion Recovery disk:

* Reboot the Mac and hold down the Option key
* Selecting Recovery as the your boot drive
This tool works flawlessly. Some of its features are get booting from the Recovery partition, allows you t perform OS X Install, run disk utility to format, partition, time machine backups and internet restores.
Note: This tool does not create a general Lion installer that can be used to upgrade other Macs or install Lion on other Macs, it’s a recovery disk.
Apple’s Notes on the recovery Disk Assistant utility:
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.
Note: In order to create an external Lion Recovery using the Lion Recovery Assistant, the Mac must have an existing Recovery HD.
To create an external Lion Recovery, download the Lion Recovery Disk Assistant application. Insert an external drive, launch the Lion Recovery Disk Assistant, select the drive where you would like to install, and follow the on screen instructions.
When the Lion Recovery Disk Assistant completes, the new partition will not be visible in the Finder or Disk Utility. To access Lion Recovery, reboot the computer while holding the Option key. Select Recovery HD from the Startup Manager.
