Tell the new installation to put the bootloader in the partition
containing the root file system, not in the Master Boot Record.  Then
you can steal the information generated in the /boot/grub/grub.conf
and add it to  the real grub.conf that Ubuntu installed.  With some
care to avoid name conflicts.

It seems that only device.map and menu.lst are readable.
No trace of /boot/grub/grub.conf
My more or less educated guess would be that I need to be looking
into /boot/grub/menu.lst .
