Erase option is disabled in Disk Utility and as well Security Option

MacBook Pro, Mac OS X (10.7.5)

    You need to use Lion's recovery partition, or a Mac OS X install DVD, or a different OS X installation, to erase the normal boot partition.

    Please post in the proper forum.  You are posting about Lion in 10.3 and earlier forum.

     

    The erase option is not disabled, you simply cannot erase a startup drive. However, you do not have to erase the drive in order to Journal it. Open DU, select your volume, click on the Enable Journaling icon in the DU toolbar. You can also do this by:

     

    Boot to the Recovery HD:


    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.


    Open DU and proceed as above. If you need to erase the drive and reinstall:

     

    Install or Reinstall Lion/Mountain Lion from Scratch

     

    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.

     

    Boot to the Recovery HD:

     

    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.

     

    Erase the hard drive:

     

      1. Select Disk Utility from the main menu and click on the Continue button.

     

      2. After DU loads select your startup volume (usually Macintosh HD) from the

          left side list. Click on the Erase tab in the DU main window.

     

      3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on

            the Security button and set the Zero Data option to one-pass. Click on

          the Erase button and wait until the process has completed.

     

      4. Quit DU and return to the main menu.

     

    Reinstall Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.

     

    Note: You will need an active Internet connection. I suggest using Ethernet if possible

                because it is three times faster than wireless.

    You can't erase a volume your booted from.

     

    Hold command r and boot the computer, select Disk Utility and the Macintosh HD partition on the left, now you can erase it. (make sure you want to do this, all files, OS X and programs will be gone)

     

    You can then reinstall OS X once you quit Disk Utility, but you need to be connected to a fast Internet connetion (and your AppleID and password) to download it from Apple's servers.

     

    How do I securely delete data from the machine?

     

    How to reinstall just OS X or erase/install OS X
