Start installing Ubuntu, choose a language, then choose your location. In the
"Select a keyboard layout" screen, choose "Go Back". This should take you back
to the "Choose your location" screen, but it doesn't; it skips back to the
"Choose a language" screen, and choosing a language skips forward to "Select a
keyboard layout". It seems to be impossible to return to the "Choose your
location" screen at all.
