found 0.97-16 thanks I just had a look at grub version 0.97-16, and /sbin/grub-install is still missing. This path is used by grub-installer in d-i beta 3, and thus the installation fail. Adding a symlink in /target from /sbin/grub-install to /usr/sbin/grub-install solved the problem. Friendly, -- Petter Reinholdtsen
