After having successfully rebooted today with 24-2, i took a security
copy of the properly working grub.cfg, and installed 25-1, making sure
that grub.cfg is updated. After that i compared both with each other,
and there was not a single difference.

Hmmm, so maybe here we have the issue? If running grub-install again is
definitely required for a workable boot configuration, then this might
be the point where it fails. I never saw any debconf prompt, and thus
didn't recognize the need to run grub-install. I have had configured
debconf to never ask me any questions with a priority less than medium.
But even after setting it to the lowest possible option i was not shown
any prompt asking to run grub-install.

What i did now was to manually run grub-install on the drive, in order
to make sure that grub is definitely updated. And this finally resulted
in a properly bootable system.

Thanks for your help!

Cheers
