I'm new to GParted. I have to resize a partition that contains root file system which is full. Previously I had Windows installed in my system. I use a 250GB hard drive and was divided into 3 drives namely C, D and E drive. After this I installed Ubuntu and used the existing NTFS file system, to install Ubuntu. Now, I need to resize the partition mounted on root file system as it is full.
Below is the link to screenshot of GParted -

What should I do to increase the size the /dev/sda6 without any data loss in GParted

  • @AvinashRaj I saw it . But, my root /dev/sda6 is locked I cannot unmount it, so what should I do to move the free space in /dev/sda3 to the right of /dev/sda6 – user3004356 Mar 7 '14 at 17:39

    you have to boot from Ubuntu live disk.So that you can be able to resize your Ubuntu partition.Before resizing, make that the partition you want to be resized should be unmounted.See the full answer. – Avinash Raj Mar 7 '14 at 17:41
  • The main problem for you, as Avinash pointed out, is that you are trying to resize a mounted partition...since it is your root partition you cannot unmount it because your system is currently running off of it. So the answer provided kamil is in my opinion the fastest and simplest way to go. – Daniel W. Mar 7 '14 at 20:25

    This is a dangerous answer that doesn't address the 'how-to' of resizing root, and remapping the UUID is a critical part of that. – nullsteph Aug 27 '16 at 15:47
  • dangerous!! I think he knows what GParted is. – kamil Sep 22 '16 at 9:52
