When I installed Ubuntu 12.04, I didn't know how to properly set the mounting points for the partitioned logical drives. So, I just set it randomly. Now when I open the Home folder I cannot see any of the logical drives on the left pane. I tried to change their mounting point but couldn't.

The contents of my fstab file /etc folder is:

# /etc/fstab: static file system information.

#

# Use 'blkid' to print the universally unique identifier for a

# device; this may be used with UUID= as a more robust way to name devices

# that works even if disks are added and removed. See fstab(5).

#

# <file system> <mount point>   <type>  <options>       <dump>  <pass>

proc            /proc           proc    nodev,noexec,nosuid 0       0

# / was on /dev/sda1 during installation

UUID=691fa0bd-350f-4378-b5c7-82d277dd83c2 /               ext4    errors=remount-ro 0       1

# /srv was on /dev/sda8 during installation

UUID=753d012e-ac3c-42fd-b388-d83115e88d26 /srv            ext4    defaults        0       2

# /tmp was on /dev/sda5 during installation

UUID=34d8c35a-7900-4acd-988d-880792849673 /tmp            ext4    defaults        0       2

# /usr was on /dev/sda6 during installation

UUID=4f7f4287-5feb-4b2b-86bb-93fe74905149 /usr            ext4    defaults        0       2

# /var was on /dev/sda7 during installation

UUID=e2933e36-7906-48ac-b2ac-93500537cd4a /var            ext4    defaults        0       2

My Partitions are mounted at the following locations:
/dev/sda5 is mounted at /tmp;
/dev/sda6 is mounted at /usr;
/dev/sda7 is mounted at /var;
/dev/sda8 is mounted at /srv.

If I attempt to change the contents of fstab file, it says that only root can change the contents.

How do I change the mounting points of the partitions such that they show up in the Home folder?
