I have a windows partition which was 500gb, then i installed ubuntu with a 40gb partition, now i am short of space, so i booted my ubuntu14 live cd and shrunk my windows paritition and got 88gb free unallocated space.
Now i want to merge this 88gb unallocated space to my linux parition.
What have I tried :- I tried to Move/resize this unallocated space from live cd, but it is greyed out.
What I want :- How to merge this unallocated space to my linux partition such that my 40gb linux becomes (40+88) 128gb single partition.
UPDATE:- I needed the 88 gb so i reshrunk it to 44 gb and gave it back to windows, now the unallocated space is 44gb, and all the screenshots are taken from Gparted by live boot. So you can see the options provided.

Follow these Steps to Allocate the unallocated Space to your linux partition.
It is because GParted does not let you to resize/move the extended partition because of the swap partition that is inside it is on, so you have to switch it off by booting an Ubuntu Live cd and start Gparted.
To Switch off the swap partition :- select "Swapoff" from the extended volume, then you will be able to move the extended partition. You might need to use "Edit → Apply All Operations" for Swapoff to have effect.
After this you can shift the unallocated space inside the extended volume, then resize the /dev/sda5 volume to add the unallocated space.
P.S. Do take backup before doing these tasks.
