I was using Windows 11 on my laptop but I wanted to install a Linux distro on the side. Therefore, I've shrunk 30GB of the OS disk and I installed Pop_Os. During the installation process, I've created a EFI and root partitions.

I now wanted to extend the ext4 partition. I was able to shrink even more the original OS disk, but the unallocated space is shown on the left when using gParted and I'm unable to resize the root partition.

Below the gparted screenshots and fdisk outputs:

Getting a bit out my comfort zone now :) How should I proceed now to expand the partition?

You need to do the resize from a LiveCD -- the nvme0n1p5 partition is currently mounted. Ext4 can be resized when mounted, but only to the right -- resizing it to the left actually means copying/moving the data to the start of the free space and then resizing the partition and that cannot be done with an active (mounted) partition. So boot from a LiveCD (the Pop installation CD has GParted so you can use that) and use the GParted Resize/Move option to resize the partition. Don't forget to make a backup first.

  • It worked. thanks for the help! I didn't do any backup because it was a clean install so there would not be any issues if I lost the data, but no problem happened so even better. Commented Jun 18, 2022 at 18:59
