Can you attach the full contents of /boot/grub/grub.cfg in Debian 12
root filesytem ?
This is a bug for Debian 13 and not for Debian 12.
The error occurs after the upgrade when grub has been installed in
Debian 13.
Which upgrade ?
It seems to be confusing for you. :-)

Debian 12 is installed in /dev/sdb2 and has been copied to /dev/sdb5.
It was not easy to boot the copy in /dev/sdb5, but after about 3 attempts it
works and the copy has been upgraded to Debian 13, after the modify of
sources.list
In the upgrade process grub has been installed in /dev/sdb5, so it is not
booted any more from /dev/sdb2.
