Whenever I turn on my computer it opens to a terminal and I have to log in there and run startx to get to my Xubuntu 18.04.3 LTS Desktop. I have no idea how to get back the normal login screen, when I press the arrow key it just cycles through the terminals and never goes back to the login screen.
The problem is I don't know how to make Xubuntu boot from the installation media and not boot into Xubuntu on the internal drive.
