I am not able to re-size hard disk partition.

MacBook Pro (13-inch Late 2011), Mac OS X (10.7)

    System will not allow the partition size of the partition it is running from to be changed.

     

    You are going to have to clone your system to another drive and then boot from the clone so that the disk is free to be changed.
