Let assume you like to install 4 linux distros
You have divided you're hard disk in 4 partitions
Let start which the distro in the last namely partition 4 install it over there and write GRUB in boot sector of partition 4 .
We do the same with partition 3 and partition 2
The distro in partition 1 we write GRUB in MBR
Normally the last distro is aware of the other distros in partition 2 up to four and updated its menu.lst or whatever it use to boot the other distros
In the menu.lst you will find all the installed distro
If this is going wrong for one reason or they other , we can always add it manually.
How exactly depends on the linux flavour in qeustion
MBR is only 512 bytes so you're menu.lst is not there.
You will find it in /boot/GRUB/menu.lst
But this only one way to do a multi boot there other ways to accomplish it.
I hope this make it somewhat clear how to do it
