----------
I did exactly what I did the last time that I installed AS 2.1.
It worked on the other machine.
The directory /boot/grub has files: grub.conf, stage1, and stage2

My grub.conf is in another post. It is very similar.
More strange info there too.
The problem seems to be more fundamental, that it can't
get to grub.conf. Not the grub.conf file itself. (Just like my
questions two weeks ago. It wasn't the hosts file, it was
that the ethernet drivers were not installed.)
