How do I know which grub version is used and how to configure it?

Well, I just want it to work like it should but right now something has screwed
it up so it references stuff on the wrong partitions etc and does not show the
actual Ubuntu version/kernel number correctly.

But on a multi-boot machine I assume that the boot-loader cannot belong to any
one operating system, right?
It must be the "master" of the system because nothing else runs until the user
has selected the menu entry to start with.

So whoever updates the menu needs to look around on all partitions for boot
information, which it seems to be doing by what Update-grub shows and yet my
actual boot menu does not show the real situation. :(

 Sigh...
