I am using Ubuntu 20.04LTS along with Linux Mint 19.3. I want to remove Mint and keep only Ubuntu.
Also, I want to assign the space of Linux Mint to Ubuntu.
How should I go with it?
Boot from the Ubuntu Live USB.
After running swapoff
in a terminal to disable the swap files, run GParted to delete the Linux Mint partition. With GParted, you define a change, then commit the change with the green checkmark, before moving on to make the next chantge.
Then you can resize the partition for Ubuntu.
You may need to edit GRUB later to remove the entry for Linux Mint.
