To make this method work, we need to have bootable media created from the Ubuntu ISO. Download the Ubuntu ISO. In my case, I'm running Ubuntu 20.04.1 LTS.

Create a bootable USB flash drive. Refer to the instructions on how to create a bootable USB drive.

Boot into the Ubuntu bootable media. When prompted, select "Try Ubuntu". This will start the Ubuntu live session.

Once in the live session, launch the terminal.

We need to identify the root file system partition. The following command will list all the partitions in the system. The important part of the output is the last section, which contains a short partition table.
