    Follow the instructions in step 5 of the article you asked this question from. If the computer shipped with Mac OS X 10.6.8 or earlier, instead of pressing the Command and R keys, insert its original DVD and press C.

    I tried the above instructions and it will not work.  I get to the disk utility and what shows is the Macintosh HD  and Disk 1 below this it shows OS X Base System when I hold the cursor over it It says start up disk OS X base system. If I click this the format and name and erase at bottom of screen do not allow anything.

     

    If I click on the Macintosh HD It shows Mac OS Extended (journaled) and the name Macintosh HD

     

      am I supposed to reformat the Macintosh HD ??.
