the only alternative was to drop into the Grub prompts and figure out what is going on at that level.
but, what I know how to use in Terminal, for the most part, just does not work.
inxi is not available, my sleuth skills are zero with the Grub commands.
is there a tutorial for that situation?
( finally got the install done, by CTRL-ALT-F1 to get to terminal window and exited that
switched back to the login screen by pressing Ctrl+Alt+F7
and the screen was sync'd up... clicked on install and it worked )
