I installed Ubuntu for the first time half a year ago, so I'm a fairly new user.
Back then I installed Ubuntu 18.04 alongside Windows 10 with a dual boot setup, with Ubuntu being the default OS. A month ago I encountered a problem, which I could not find a solution to, so I had to reinstall Ubuntu from a bootable USB. Luckily, Ubuntu found that it was already installed and suggested to just overwrite the current installation of Ubuntu with a fresh one, which I of course selected.
Ubuntu works fine, but I don't have a lot of space, and I've had several warnings saying that The volume “filesystem root” has only XX MB disk space remaining. I have removed any unnecessary files to free up space, until I realized that my "main" drive is not mounted.
When I run df -h in a terminal, it outputs the following:

where the "106 GB Volume" used to be my "main" hard drive, where I had many of my programs, pictures etc, and by default it is unmounted. When I click it to mount it and run df -h again, it outputs the following:

where the 106gb drive is now added (I deleted everything on it, hence the usage %).
When restarting the computer, the drive is unmounted once again.
My question is: How can I make this drive my "main" drive once again, automatically mounted when the computer is booted and automatically the drive applications are installed onto, instead of the root, which (as far as I'm concerned) should only be used for system critical files and applications. This was not a problem before I reinstalled Ubuntu.
Please tell me if I need to provide any more info. Thanks in advance.
