Dear Maintainer,

   * What led up to the situation?

	Installation of Bullseye from "debian-live-11.1.0-i386-xfce+nonfree"
	with fresh formatting of the "/" and swap partition of the SSD.
	Everything worked as expectet until the installation of the grub2:
	This part repeatedly led to reporting of a serious error without becoming more precise.

	The following boot attempt failed, and ended in a grup-prompt

	Almost a year ago, Debian 10 was installed on the same hardware without any problems.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

	Ineffective:
		"boot-repair-disk-32bit", it led to the same result.
		But: In the log there was the hint to the problem:
		"grub-install: error: failed to get canonical path of `/cow'."
	Effective:
		Booting the live system
		mount /dev/sda1 /mnt
		cd /mnt
		grub-install --recheck --root-directory=/mnt /dev/sda

   * What was the outcome of this action?
	After that, the system could be booted as usual, with the difference that there is now a textual Grub menu instead of the graphical one.
