I am trying to expand the size of my root directory as I am running low on space. I have tried resizing it from a Live USB and it won't let me.

The text in red is the mounting point (according the partition manager) when booting from the drive. /dev/sdc5 mounts to /boot/efi and /dev/sdc6 mounts to /

fdisk -l /dev/sdc yields:

Disk /dev/sdc: 29.3 GiB, 31406948352 bytes, 61341696 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x4e13a3a7

You don't have any unallocated space after the extended partition into which you can resize it. You can either reinstall or if you want to take the arguably more fun approach, perform the following gymnastics:

1. Create two primary partitions using the unallocated space: one will be your new ESP, which you can make 256MB (or even 128MB) and the other will be new your rootfs. Create them in that order.


2. At this point you'll have two ESP's, so remove the original ESP to avoid any conflicts. Note that deleting the partition will not wipe out the data; The partition can be revived with the information I had you add to your post.


3. Format the new partitions accordingly and copy your files over.


4. Check the /etc/fstab in the new rootfs, and update it if needed.


5. Boot from the USB drive to ensure everything is working.


6. Delete the extended partition. You'll now have unallocated space after your rootfs partition.


7. Resize the rootfs partition into the unallocated space. You'll need to boot from another system to do this.


8. Resize the rootfs to grow into the now larger partition, using resize2fs.
