some months ago I decided to create a new partition on my 500GB drive to run Ubuntu in dual boot with Windows 10. I was pretty sure that 97GB (100000 MB) would be more than enough for what I was trying to do, but now I am running out of disk space (I need roughly at least 60 more GB). Fortunately my Windows 10 partition (/dev/sda4) had a lot of empty space to free, so I shrank that partition and I obtained a 97GB of unallocated space. The problem is: how do I add that space to my current root partition (/dev/sda6) without breaking anything?

  • Little key icons show partitions are mounted. You cannot change mounted partitions, so use live installer. Actually with gpt I have found I can create a new partition in unallocated space as long as I do not try to modify mounted partitions. You then could create /home or /data partition and use that as an alternative.

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/sda6 partition all the way left
  • resize /dev/sda6 right side all the way right
  • click the Apply icon
