The update-grub(8) script is used for this. It scans /boot for kernels
and adds them automatically. If you install a new kernel and its not
in the same /boot as the other kernels likely update-grub will just
update a menu.lst that is never used. (because the grub installed to
the hard drive reads the menu.lst from the other installation) You'll
have to add the entries for the new kernel manually after booting into
the other installation.
