I'm new to GParted. I have to resize a partition that contains the root file system which is full. Previously, I had Windows installed on my system. I use a 250GB hard drive and it was divided into three drives namely the 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 as the root file system because it is full.

Below is the screenshot of GParted:

What should I do to increase the size of /dev/sda6 without any data loss?

  • @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 07 '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 07 '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 07 '14 at 20:25
  • Why is this question off-topic? It is not specific to a particular release. – Sam Brightman May 21 '15 at 15:20
  • This question can still be relevant to other Ubuntu versions - it is not version specific in the latest edit, and just because it said 12.04 doesn't mean it's not still useful/relevant. – Thomas Ward Jan 02 '17 at 14:33
