(Thank you David for responding to my previous question.)
On my Laptop, I have several OS's (Win7, MDA2007, MGA2, MGA4, MGA6 and Ubuntu 16.04, I think) and each time I've installed an OS, I think I've installed the GRUB menu with-in the OS's partition.
So, as I boot into the MGA6 GRUB, if I select MGA4, I then boot into the MGA4 version of GRUB which offers Win7, MDA2007, MGA2 and MGA4. If I
then select MGA2, I then boot into its version of GRUB which offers
Win7, MDA2007 and MGA2. And so on!
Of course, if I select Win7, I go straight there.
AS I recall this is because I've always installed the GRUB menu with-in
the OS's partition .... as I don't ever recall anywhere, in the OS installation process, being able to install GRUB elsewhere so that I'd
only have to make an OS selection once and then be taken directly to
that OS.
As I typed, I guess this selection is made somewhere with-in the installation process, .... but, it seems, I keep missing that selection.
What should I be looking out for, please??

Grub menu is stored in /boot/grub2/grub.cfg
Proper way to update grub.cfg is boot the desired OS and run
update-grub2
grub2 will then scan the drive and build a new /boot/grub2/grub.cfg
for that install.
(Thank you David for responding to my previous question.)Been there, done that. Maybe you need refind. It is the only popular bootloader I know of that isn't tied to a specific distro on your system.

Ah!! So this means that after running 'update-grub2' in my soon to be install MGA8, if I were to select the MGA6 entry from the Grub2 menu, it would start running MGA6 directly ...... RIGHT??

You need to install grub legacy (grub-0.97-50.mga8) in order to be able to install to a partition boot record, instead of to a drive's master
partition
table. The drive must use a mbr style partition table.
grub2 only supports being installed to a master boot record, not a
partition boot record.
What should I be looking out for, please??
I'm pretty sure the installer now only supports installing to a master boot record, not a partition boot record, so you'll have to install to a mbr, then manually change it to a pbr after install.

I don't know if I should ever question what you type, David, but that
seems backwards to me.
I thought I would have been installing Grub2 into the partition in which
MGA6 resides, then, if I selected MGA4 from the MGA6 Grub2 menu, then
the system would have had to leave the MGA6 partition and look elsewhere
(the MBR, maybe) to find out which partition MGA4 was installed in and,
then, would find the MGA4 Grub2 menu there from which I had to select MGA4.
