Hide boot drive from nautilus

I have a boot drive which I don't want to show up in nautilus. How do I edit /etc/fstab so that the boot drive doesn't show up as a mountable device.

Current /etc/fstab:

# /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/sda2 during installation
UUID=595815c2-d882-4ec8-a2cd-cce70471167c /               ext4    errors=remount-ro 0       1
# /boot was on /dev/sda6 during installation
#UUID=1340a336-66ca-4743-a6e4-41a307af2dda /boot           ext4    defaults        0       3
# swap was on /dev/sda5 during installation
UUID=afa49f1d-d505-4166-82a2-2f44548a48c6 none            swap    sw              0       0

UUID=deb86039-528a-45f3-b5f9-ce528740c94e /data_hdd ext4    defaults    0   2

The drive shows up in Unity's launcher as well:

You'll need to create a configuration file for udev.

Run gksu gedit /etc/udev/rules.d/hidden-partition.rules, and paste in the following content:

#sould be placed into /etc/udev/rules.d/
ACTION!="add|change", GOTO="hide_partitions_end"
SUBSYSTEM!="block", GOTO="hide_partitions_end"
KERNEL=="loop*|ram*", GOTO="hide_partitions_end"

################################################## ############################

#Hide sda6
KERNEL=="sda6", ENV{UDISKS_PRESENTATION_HIDE}="1"

################################################## ############################

LABEL="hide_partitions_end"

The boot partition should be gone after reboot.

PS: The method has been working well for me for hiding a Windows partition. I've don't have a boot partition to test, but hope it will work as well.
