Making A Partition with Gparted - Unmount?

This is a screenshot of my partitions. I want to extend the /dev/sda5 partition to all unallocated space (27.03 GB).

I tried unmount the ext4 partition to increase it but i got this error message.

The partition could not be unmounted from the following mount points:

Most likely other partitions are also mounted on these mount points. You are advised to unmount them manually.

You cannot unmount the partition you have booted Ubuntu from. boot from a Live CD/DVD/USB and choose Try Ubuntu. Then use GParted. –  user68186 Jan 10 '13 at 19:29

You can't resize the partition Ubuntu is currently running from.

You need to boot the install media, LiveCD or USB drive, choose the option Try Ubuntu without installing. Then when it loads the desktop, you can run GParted and resize the partition as you want.
