Simple, run

update-grub

after a fresh install or after you upgrade your kernel. Ref:

Yeah, I am wondering why update-grub can't do that myself.

Why not just chain load them? Whatever OS, even window$, grub's chain load can boot them fine, as long as the partition is bootable by itself. Ref:

http://xpt.sourceforge.net/techdocs/nix/disk/boot/boot06-Grub/ar01s06.html#Editing_the_GRUB_Menu

If the partition is not bootable by itself, especially when you install the grub to MBR, you can still put an entry in you main menu.lst, eg,

configfile (hd1,0)/grub/menu.list

so as to refer to its boot menu from the main boot partition.
