Thanks Dennis. I should've mentioned this as a potential clue. When I did the upgrade from 15.10 to 16.04LTS I got through the entire update fine. The last thing to do was to reboot. So I clicked on reboot. Well, when I did nothing happened. It wasn't like a normal reboot at all. The screen just went blank. And stayed blank. For maybe 2 or 3 minutes. After that time had elapsed I thought the computer had powered off (it had not) and so I pressed the power button,thinking I was turning it on.
I wonder if that may have had something to do with the subsequent problems.

I have Enlightenment, a couple of flavors of Gnome, LXDE, Unity, and XFCE installed as GUIs, and can select which to use from the Login screen. The default is the last one used.

This is my first experience with the grub boot menu. I've never had more than one OS, never dual booted, so usually I just turn on the power switch and the computer boots up.

The computer no longer boots from the power switch. It only boots from the GRUB loader and only the 15.10 kernel. Not the two 16.04 kernels that are there. It used to boot from the power switch to the latest 16.04 kernel but no longer does.

^I'm not quite sure what you mean.

When I simply push the power button the computer does not boot. Period.
This is how I go about starting the computer.
1) I turn on the monitor
2) I push the power button.
3) As the DDR3 and Slave/Master stuff starts coming on I hold down the Shift key.
4) Eventually the grub boot menu appears
5) I choose the 'advanced options'
6) There I see my three kernels (including 'upstart' and 'recovery' versions)
7) I arrow down to the 15.10 version
8) I hit the Enter key
9) The computer comes on (and in less than 2 minutes)

Normally I don't see a grub screen. Or at least I've never noticed it. And now, thank goodness for the grub screen because it let's me choose the 15.10 kernel as the two 16.04 kernels don't boot.
