OK, thanks.
I will give up on this then and write a sticker on the monitor with the correct
identification for future use...

One can wonder why the first Ubuntu entry always comes out with no extra info at
all whereas the following have both the version number and the partition name as
identifiers...

Like this: 

* Ubuntu
  Advanced options for Ubuntu
  Windows boot manager (on /dev/nvme0n1p1)
  Ubuntu 20.04.3 LTS (20.04) (on /dev/nvme0n1p6)
  Advanced options for Ubuntu 20.04.3 LTS (20.04) (on /dev/nvme0n1p6)
  UEFI Firmware Settings


The server very seldom is rebooted, only if required by an Ubuntu upgrade or
when I want to copy the partition as a backup and therefore need the Ubuntu
Desktop to start where I can use GParted.
