I was able to setup a successful unattended install using Ubuntu 14.04 server (ubuntu-14.04.2-server-i386.iso).
However, when I attempt to do the same with Ubuntu 18.04 server (ubuntu-18.04.1-server-amd64.iso) it keeps on booting up and displaying the language selection.
How to I make the language selection disappear and show the main installation selection menu?
