Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
I updated debian with
su
apt update
apt upgrade

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
grub from debian installation was installed during debian package update

   * What was the outcome of this action?
debian version of grub is now installed (likely in MBR)
This version does not show an option to start kde neon
   * What outcome did you expect instead?
the installed debian grub version detects KDE Neon and provides an option to start the installed KDE Neon besides the option to start debian

Hi,

what's the reason that you still use the old GRUB Legacy instead of
GRUB 2?

I suggest using GRUB 2 with os-prober installed.
Though you need to enable usage of os-prober in /etc/default/grub with

GRUB_DISABLE_OS_PROBER=false

GRUB 0.97 won't get any fixes from us anymore.

Hi,

grub was just a guess of the package name from my side. It should be grub 2:

The grub boot selection page says GNU Grub 2.06-13+deb12u1.

Br,

Michael

Then this probable is a case of not installed and not (by default)
enabled os-prober.

So install os-prober if it's not already.

And in /etc/default/grub

GRUB_DISABLE_OS_PROBER=false

And last

sudo update-grub

os-prober won't be enabled by default anymore.
