thanks. Reinstallation with 'grub-install /dev/hda' from within Debain
worked for me fine.
For completness I should mention here that Ubunutu boot menu entry was
created, however not the Ubunutu recovery boot menu entry.
Would it be worth to file an error report against debian-grub?

There are also cases, when Debain distribution can no longer be started
from the boot menu. Reason may be a MBR virus that corrupted Grub from a
MS Windows partition or e.g. MS Windows installation subsequntly to the
Debian installation, which replaced Grub in the MBR by directly starting

After booting from install CD, e.g. the Red Hat installer allows
reinstallation of the boot manager (and doing hard disk partitioning
with Fdisk) without being required to perform subsequently a full Linux
installation. So far I've been missing this option in Debian installer...

You can not and that will not be supported in future. Boot loader

+when starting the 'systemtools-> system start' tool (Translated

installation of Ubuntu. This information no longer reflects the current
grub configuration nor any change to the confguration shown here does
change grubs boot behaviour.
This is because you have different /boot directories for each linux
installation. Grub uses only one of them, based on the "groot=(hdx,y)"
line in /boot/grub/menu.lst when GRUB was installed.
Currently it is using the one from the Ubuntu installation, not the one
from the Debian installation.
What you need is to do is RTFM on how GRUB works.
How can I reinstall grub from my Debian installation?
I think even after installation of Debain, 'base-config' should allow
reinstallation of Grub. Did I miss anything here?
You can reinstall grub using grub's own command line tool grub-install
(see 'man grub-install').
