I am new to Linux and have installed Ubuntu and Mint in a dual boot on a old Dell Optiplex. I like Ubuntu and would like to uninstall Mint and only use Ubuntu, but use the entire hard drive to do so. How do I accomplish this?
Thanks. Not sure that I know how to follow your instructions being new to Linux.
Removing OS from Dual Boot computer, and recovering HD space.
Delete all files in the Mint partition.
Using GParted, resize the Ubuntu partition to take up the entire hard drive.
