OS X Lion: Using FileVault 2 and Lion Recovery
Learn how to use Lion Recovery if you've enabled FileVault 2 in OS X Lion, or if you have enabled a firmware password on your Mac. FileVault 2 lets you encrypt the contents of your entire hard drive.
To start from Recovery HD with FileVault 2 enabled
- Restart your Mac, and immediately hold the Command and R keys.
- Once the Mac begins to start into Lion Recovery, let go of those two keys. Lion Recovery will load normally and you can perform any of the tasks that are supported.

Some startup keys don't respond if both firmware password protection and FileVault 2 are enabled
Some startup key combinations that you can use when your Mac starts, such as those which use the Option or Command keys, may not respond if a firmware password has also been enabled.
If you have a firmware password enabled on your Mac, you must successfully enter that password before you can boot to another startup volume, or before you can access the Startup Manager.
