Different problem.  Grub 1 can not be expected to know about 
Grub 2.  Grub 2 should know how to handle a Grub 1 system, but 

There are many many ways to get around this, so many that it 
gets confusing sorting out which method to choose.  One of the 
more explainable methods is to make a habit of installing 
systems with boot loaders in their own root partition rather 
than in the mbr.  Then you are left with the comparatively 
simple problem of having something in the mbr be able to find 
all of the other boot loaders.  

eg.  Starting with one distibution on your system, let's call 
it A, with a boot loader in the mbr.  Install distribution B 
with its own boot loader in its own root partion.  Reconfigure 
A's boot loader so that it can chain B's boot loader.  Next 
time you reboot you should see A's Lilo/Grub1/Grub2 screen 
with a menu item for B (plus all of the original A options) 
select B and then you should see a second boot loader, for B.  

You might need to look up "chain".  

In Lilo you want something like: 


In Grub 1 you want something like: 

title m1_grub
root (hd0,8)
chainloader +1

You might get what you want by using Mageia's Control Center 
and selecting "Other" operating systems - assuming that the 
other installations already have a boot loader in their 
respective root directories.
