Not possible to enlarge partition dimensions.
Not possible to enlarge partition dimensions.
The issue may stem from system limitations or file system constraints. There are no obvious causes, but checking for storage errors or driver issues could help.
In short: The lock symbol next to the partition indicates it's mounted. The mount location shows it's attached to the root directory, meaning it's the active boot partition. You can't change or unmount it while it's running. To update the partition, create a new bootable USB or CD, boot from it, and adjust the root partition there. Alternatively, use tools like Gparted Live USB. Once in a live setup, you'll notice the partition is on the right side of the disk layout. You'll need to shift it left, which moves data physically, taking time. After repositioning, expand it into the remaining space. Be careful—changing its size may alter its UUID. If the UUID changes, you might need to edit /etc/fstab to point to the new ID before you can boot again.
