Q: This disk is locked

MacBook Pro does not boot normally. Log in screen doesn't appear. I only see the Apple logo and waited for it to load.

Internet says Reinstalling Mac OS X could fix the problem.

 

I'm currently on Recovery Mode.

 

I selected Disk Utility.. clicked "Macintosh HD" and the "Verify Disk" and "Repair Disk." It says this disk is corrupted and that it needs to backup.

 

I'm trying to reinstall Mac OS X Lion on Recovery Mode.

Two disks appeared:

"Recovery HD"

"Macintosh HD"

Both disks are locked

 

Is there any way to unlock it?

If not, then what other options do I need to do?

I don't know what to do with the Restore From Time Machine Backup.

 

What I've already tried:

 

Both Safe Mode and Verbose Mode

Single User Mode

Reset The NVRAM

MacBook Pro, null

    Also why can't I edit my question?

    I'm trying to add a detail on the headline/question bar

     

    I clicked the down arrow at the upper right and it only showed "bookmarks"

     

    I went to History and clicked on the page where I was still allowed to edit the post

    So I added the detail and clicked "Post"

    A text appeared.. "You are not allowed to create or update this content"
