Hi Julian Klode. Thanks for your info. Yes, I changed the line in /etc/default/grub while trying to resolve boot failures.
After making the correction you recommended: - I ran update-grub, - restarted, ok, - ran Software Updater and got the error- grub-install: error: failed to register the EFI boot entry: Operation not permitted. Grub failed to install to the following devices: /dev/nvme0n1p1 Not sure what to do about this; maybe I'll be back to reinstalling the OS.
