I'm looking at your system through a tiny peephole!
All I've done is to conjure up a scenario that doesn't
AFAICT contradict anything you've written.

Booting is a multistage process. By means of an MBR or EFI, you
reached the Grub menu, which you photographed. At the top, it says:
  GNU GRUB  version 2.06-13+deb12u1
which is the bang up-to-date bookworm version of Grub.
Having photographed this menu, and commented on its
lack of a particular menu, all I see is evidence of bookworm.

Now, if you press Return while in the state the photo recorded,
then you'll end up in a bullseye system. Hence:

> To my understanding, booted into Debian 11 on hd0.

But I have no /evidence/ that there's any connection between the
grub.cfg you were editing and the grub.cfg that displayed that
screen. I would need to know what else was on the machine and its
disks to do anything more than guess from shaky assumptions.

I think you mean MBR on hd0. Is hd0 the legacy disk and
hd1 a new one? Would it be correct to assume that the machine
booted from the MBR, and still does? Can we assume that you
haven't tried to install Grub onto hd1? There's a stack of
unknowns at this end.

Cheers,
David.
