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. > > And a 14-month old bullseye system on hd0, which is currently running? > > Yes. > root@imager:~# cat /etc/debian* > 11.11 > > > The system has booted into a bookworm Grub (deb12u1). > > I don't understand. 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. > A new-to-me detail is hd0 having FAT and hd1 having GPT. 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.
