Thanks for mentioning me and giving the credits,
I added an easier solution to that post
for those who dont need/want the swap and dont need to expand their partition.
Option2 :
If you have 16GB USB/SSD/HDD and dont want/need swap partition.
Just open /etc/fstab with
gksudo gedit /etc/fstab
and add a # before the UUID in swap line
# swap was on /dev/sda5 during installation
#UUID=cdba7b01-5ae6-4104-9a6e-f723b8bd87ac none swap sw 0 0
reboot and have fun.
