How to expand root partion in Ubuntu 19.10

Question

I want to expand my root partition /dev/sda5 by adding unallocated space. Primary Partition is 30 GB and I want to add 20 GB more so that it can be 50 GB. I tried using gparted and live CD but doesn't work.

Do it from a LiveUSB. But you'll need to reinstall grub, because you move the start point of /. — Pilot6, Mar 06 '20 at 19:40
@Pilot6 We never got an answer from a previous OP where you indicated that a GRUB install would be required. I've put together a similar answer here... let's see if a GRUB install is required, or not. — heynnema, Mar 07 '20 at 19:29

It looks like you have:

A Primary Partition, which contains

/dev/sda1
/dev/sda2
/dev/sda3
/dev/sda4
Unallocated space

and a Secondary Partition, which contains

/dev/sda5

You'll need to seek advice on shrinking your Primary Partition. I'm not going to get more detailed, because I'm just guessing.

Re your picture: Observe the keys next to /dev/sda2 and /dev/sda5. They're indications that these partitions are mounted, and that gparted won't change /dev/sda while they're mounted.

dev/sda 1,2,3,4 are windows partion and dev/sda4 is ubuntu. Want to merge unallocated space to dev/sda4. – Shivang Saxena Mar 07 '20 at 03:50
This has incorrect information, AND it doesn't answer the question. :-( – heynnema Mar 07 '20 at 19:26

Note: I believe that you mean you actually want to increase /dev/sda5 (not /dev/sda4)...

Make sure that you have a good backup of your important Ubuntu files, as this procedure can corrupt or lose data.

Keep these things in mind:

always start the entire procedure with issuing a swapoff on any mounted swap partitions, and end the entire procedure with issuing a swapon on that same swap partition
a move is done by pointing the mouse pointer at the center of a partition and dragging it left/right with the hand cursor
a resize is done by dragging the left/right side of a partition to the left/right with the directional arrow cursor
if any partition can't be moved/resized graphically, you may have to manually enter the specific required numeric data (don't do this unless I instruct you to)
you begin any move/resize by right-clicking on the partition in the lower pane of the main window, and selecting the desired action from the popup menu, then finishing that action in the new move/resize window

Do the following...

Note: if the procedure doesn't work exactly as I outline, STOP immediately and DO NOT continue.

boot to a Ubuntu Live DVD/USB
start gparted
move /dev/sda5 partition all the way left
resize the right side of /dev/sda5 all the way right
click the Apply icon
