When I installed Ubuntu dual boot on my windows machine, I just did a 10 GB partition for installing the dual boot. But later I realized that I need much more than just 10 GB. Is it possible to just extend the disc space without uninstalling and reinstalling Ubuntu?

    Sure, it depends on your hard drive and your partitions. The best for you would be to use gparted and post a screenshot of your partitions to see if it's possible – Félicien Feb 27 '18 at 14:28
  • Please be more clear, do you reefer to extend root partition? could you share df -h output and describe which partition do you want to extend? – Alvaro Niño Feb 27 '18 at 14:28
  • There is no "Defragment drive" option showing after I select my windows partition – Sayan Saha Mar 04 '18 at 06:29

Let's assume you've got a swap partition between windows' and ubuntu's one (something like EFI/boot manager - Windows - Swap - Ubuntu) as it is the trickiest scenario.

  • First, boot on Windoze and defrag you hard drive (Start menu > search for "defragment" and do "Defragment drive" after selecting your windows partition).

  • Then, resize the Windows partition (search for "disk management" and right-click on your windows partition, select “Shrink Volume” from the menu and free the space you want to add to your ubuntu.

  • Next, boot via a live-CD or live-USB (see Create a bootable USB stick on Windows | Ubuntu tutorials)
  • Launch GParted, you should know have this kind of configuration : EFI - Windows - Free space - Swap - Ubuntu
  • Right now, all you have to do is swipe the swap space to the left (right click, resize/move and click-n-drag it to the left) and expand the ubuntu's one (right click, resize move, expand via clic and drag).
  • Press on apply and agree to the warning.
