Why can't I use my unllocated disk space?

Question

I want to increase my /home partition size and merge in the unallocated disk space. How can I do this please?

can you tell me the maximum number of primary partitions allowed on a disk and how many you have? :) — Rinzwind, Nov 10 '16 at 15:57
He does not seem to have a specific /home partition. Maybe the recommendation should be to have the unallocated space made into the /home. However, the OP would need help to move the current user files from where they currently reside to the new location of / home. — Juan Antonio, Nov 10 '16 at 17:19

You can't increase the space because they are mounted, in use. To increase that space you must boot into a live GParted session from a bootable USB or disk. I hope that helped.

According to this: http://askubuntu.com/questions/24027/how-can-i-resize-an-ext-root-partition-at-runtime/109360#109360 it can be done without login out. I agree with @Arynn though that it best to do it booting from a live USB. Make sure you backup all your files before though. – Juan Antonio Nov 10 '16 at 17:16

Your home partition sda5 is part of the extended partition sda3. You can only increase your root partition sda5 by 3.86 GiB.

The only way I see is to move your sda5 out of the extended partition sda3.

I would recommend to back up your disk first before doing anything.
