Extend Ubuntu Storage from Unallocated Space

• First Create a Bootable USB stick with any Ubuntu OS.
• Then Boot from that stick. In this way, you can unmount the other disks and OS. It won't work when the disks are mounted. So, you can't use Gparted when you are already in a running Ubuntu.
• Use Gparted to Extend the partition of the desired volume. Install Gparted this way: sudo apt install gparted.
