Thanks to Tony's tip I have got the system up again.

Appearently the manual installation of grub as described above does
not work, while the 'dumb' installation using "grub-install
--no-floppy /dev/hda" works. I will have to look into grub-install to
see what it does exactly and what the difference is with what I was
doing manually.

Thanks you all for your answers!
