Poor description by me...

The UEFI boot menu looked like this before I updated it:

* Ubuntu
  Advanced options for Ubuntu
  Windows boot manager
  Ubuntu 18.04.6 LTS
  Advanced options for 18.04.6 LTS
  UEFI Firmware Settings

In this case I *know* that the Ubuntu 18.04.6 LTS is actually my migrated Ubuntu
20.04.3 server and "Ubuntu" is the 20.04 LTS Desktop.

I did not want the text to show misleading stuff....

OTOH, when I set the PC boot priority to "Legacy first" then the menu looks like
this:

* Ubuntu
  Advanced options for Ubuntu
  Ubuntu 20.04.3 LTS (20.04) (on /dev nvme0n1p5)
  Advanced options for Ubuntu 20.04.3 LTS (20.04) (on /dev nvme0n1p5)

Again the top Ubuntu is the desktop and I originally had to start that and then
use update-grub to get it to change into into this.
Before that it also showed 
Ubuntu 18.04....

So here I only have 2 operating systems, both Ubuntu, and no Windows.

And this is what I wanted to remedy without realizing that the grub contents
depends on which mode the PC itself boots into...

So it was really impossible since Windows i UEFI-only!

Now I have set the PC back to UEFI first boot mode and all is well, I can boot
into all of the 3 operating systems.

I also managed to set the default to be the server version of Ubuntu.

What I *really* would like to do is to edit the text shown on the UEFI boot menu
to *clearly* state what it is like so:

  Ubuntu 20.04.3 LTS Desktop
  Advanced options for Ubuntu 20.04.3 LTS Deskto
  Windows boot manager
* Ubuntu 20.04.3 LTS Server
  Advanced options for Ubuntu 20.04.3 LTS Server
  UEFI Firmware Settings

But googling gives me no hits on changing the boot menu texts.
