Re-run Grub???

[MillTek <Mill.Tek@verizon.net>]

Now that I have Sarge loaded on one of my partitions, I would like to 
re-run Grub so that it will re-scan the partitions to make the boot menu 
(where you pick the OS you want to load).  Is there a way to do this??  
If you know can you show me the commands. (I did go to the grub website 
but they have an all-new grub and an older one and I haven't a clue 
which one Sarge uses)


Thanks,
Jim
