How can I unlock the Macintosh HD to reinstall OS X Lion?

I am trying to reinstall Mac OS X Lion on my mac and it says the HD is locked. I cannot turn my Mac on because it shuts off while its booting up. A gray bar appears on the loading screen then shuts off. I am trying to reinstall Mac OS X Utilities from Recovery Mode.
