The GRUB packaging is almost certainly configured to install GRUB to the
wrong place, i.e. not the place from which your firmware actually boots.
I suggest running "sudo dpkg-reconfigure grub-pc" and fixing its
configuration in whatever way is appropriate to your system.

[Carsten Wolf]

indeed this was a configuration problem.

while repeating: "dpkg-reconfigure grub-pc" the misconfiguration happened
at the decition where to write grub to. either into the partition of
rootfs or outside into raw-dev. which was the correct one.

thank you giving me the tipp - system is booting now perfectly
carsten :)
