Q: I'm trying to get my MacBook restarted and re-install OS Lion.  The hard drive comes up as "Locked".  What do I do now?

I'm trying to unlock my daughter's MacBook and reinstall OS X Lion.  When I start the re-install process, a message comes up that the hard drive is 'locked'.  What do I do next?  Please advise.  thanks,  Jim
