If you are able to get to a x session (GUI) I would adjust grub with grub-customizer. You can do this from command line, however, it would mean adjusting /etc/grub.d files.
sudo add-apt-repository ppa:danielrichter2007/grub-customizer ; sudo apt update ; sudo apt install grub-customizer ; grub-customizer

However, I would probably would just tell grub to not display the menu. As long as you're going to manually enter the GRUB_DEFAULT option in /etc/default/grub
I also forgot to tell you to run update-grub after you edit /etc/default/grub
So this is what you should do.
sudo cp -p -v /etc/default/grub /etc/default/grub.bak
sudo nano /etc/default/grub
(Change GRUB_DEFAULT=0 to GRUB_DEFAULT="Ubuntu, with Linux 4.15.0-48 generic" ) (Make sure you include the double quotes, "")
(Also add this any where in the same file, just make sure it has it's own line to itself, GRUB_DISABLE_OS_PROBER=true ) (Ctrl + O then Ctrl + X to save and exit)
sudo update-grub
sudo systemctl reboot
That should force that particular kernel to load on it's own, without a grub menu at boot time.

Many thanks Jared,
I will give this a shot tomorrow. I don't think it will fix the restart issue but perhaps this kernel is magical. I will find out. Any idea why my user name would show up in the Bios boot order? Do you think it's something I could delete safely?
Cheers

See if that will do what you're asking. TBH I'm use to systemd-boot, not grub. It's been a while since I've used grub. If that change broke things, you can move the grub.bak file back to /etc/default/grub

I tried a bunch of fixes but found one that worked! I edited / "etc/default/grub" and manually changed the screen resolution to 1366x768. that may have worked so I shutdown (hard) and booted (after, once again, moving my user name down in the boot order in the Bios) and successfully bringing up the Grub menu. I arbitrarily picked 4.15.0-48 generic and lo and behold Wifi, sound, resolution, xrandr output shows many screen res. options and things seem to be ok, for now. I would like this kernel to be the first choice for booting. I'm sure there is a simple way to do this. can anyone enlighten me? I would really appreciate it but I can also search and I'm sure there is a solution to be found.
Talk about Ghosts in the Shell!!
Thanks for your indulgences!
