If you were worried that you had no recovery hd for Lion or a hard copy of a recovery partition for Lion and want to know how to create a Lion boot recovery disk, then Lion Recovery Disk Assistant is all you need. To access Lion Recovery Disk Assistant, reboot the computer while holding the Option key and then select Recovery HD from the Startup Manager. Note that when the process is complete, the new partition will not be visible in Finder or Disk Utility. Voila, you've got a hard copy of Lion to restore it from in case of hard drive failure. To use it, simply download Lion Recovery Disk Assistant, connect an external drive or USB stick to your Mac, launch the assistant, select the drive where you would like to install, and follow the on-screen instructions. Note however that it does not create a Lion recovery USB stick/DVD - it simply creates a partition onto which you can redownload Lion from the Apple store and restore Lion to your system. Lion Recovery Disk Assistant will allow you to reinstall Lion, repair the hard drive using Disk Utility, restore Lion from Time Machine or just browse the web with Safari.

Under Erase tab, select Mac OS Extended (Journaled) format and click the Erase button. (This may take a minute or two.) Plug your USB drive into your Mac and launch the Disk Utility application Select the USB drive on the left menu, Erase tab. Apple doesnt sell Lion on a disk or flash drive, which doesnt give you much of an option to perform a clean install. Currently, Lion creates a Lion boot recovery on your hard drive when you install it but that's not much use to you if your entire hd fails. Double-click InstallESD.dmg to open (or mount) it on your Desktop. The tool will allow OSX lion recovery for users that suffer total hard drive failure.
