I know there are many questions about this topic, but I could not find an answer to my particular case. I have a dual-boot configuration on my 500 GB single hard drive, and I needed to add some space to my Ubuntu.

I have freed 7292 MB of space inside Windows in order to fix that, but now I am in the condition of being unable to add that space to Ubuntu (40 GiB partition), even if the free space appears to be adjacent to my root partition.

Here's a screenshot of my hard disk situation:

How do I add the free space to my Ubuntu partition?


First, are you booted into your Ubuntu system? If so, you can't make any edits to its partition. Reboot into a live system.

In your live system, after you've set the unallocated space, right click on the Ubuntu ext4 partition and click "Resize/Move." You should be able to move the partition to the start of the unallocated space and increase its size.

  • Thanks for your help. Yes, I am currently inside Ubuntu. In order to boot into a live system, do I have to have something like an .iso of an Ubuntu image, for instance? Or can I do it in the bios?

  • Yes, you need a piece of bootable media (for example, a USB stick) with the live ubuntu image flashed onto it. Take a look at ubuntu.com/tutorials/…

  • Sorry, one more question - Will this process delete my files or will it just let me add those 7 GB without any issue?

  • Since there's nothing on the 7 GB, you won't lose anything. However, resizing and moving partitions is somewhat risky, and I would recommend backing up the data on the partition you're moving and resizing (ubuntu partition)

  • Well, I actually meant files inside my root partition (ubuntu partition), but I think your answer still solves my doubt. Thank you once again :)
