During a standard install at the start of the configuration section
there is a point where there is a message about
"PREPARING BOOTLOADER" please be patient, searching for other
systems, this may take a while, or somthing similar. Then the
Summary pops up.
It could be done before that, immediately after partitioning.
Perhaps if the advanced button were pressed?

It would make most sense to start with a bootloader in the MBR
then go to a root partition bootloader and finaly an operating Lystem,
but LiLo and GRUB let you go "up" a level back to the MBR's
bootloader, or "sideways". e.g. From /dev/sda to /dev/sda12
to /dev/sda1 to /dev/sda to /dev/sda2 to an OS. It can even
loop to itself, pointless but it works.
If you want to do things like that, then you need to be
very careful about how you label things.
Do different things get listed in Mageia's bootloader config
depending on whether it is written to the MBR or the root
partition? Find everything if going to MBR, only list Mageia
stuff (and "back") if going to the root partition?
BTW I was assuming that every distribution has its own tools.
If your "master" installation is Mageia (or even if it is not)
you can use drakboot to add chainloader commands to Mageia's
GRUB or LiLo configuration.
Sig goes here...
