I am having a trouble in merging two unallocated partition. Can anyone help me with this?
The problem that I found different is, the unallocated partition seems to be inside the /dev/sda3.

I suspect that they can't be merged because they are not next to each other. Try moving sda 5 and sda 4 all the way to the left or right so the unallocated areas are next to each other and see if you can merge them then.
Good luck.
