Yes, and it will until you change the bootable flag on
hda2. You can leave hda2 as bootable and just make
hda6 bootable also, if thats what you want.  I would
just have one bootable.

You select which one you want during bootup when the
grub menu starts, just hit escape to open the
selection.  You will see an entry for windows and an
entry for ubuntu for each kernel you have installed
and also a rescue entry for each of these entries.. 
Assuming you are using grub as your boot loader and
not lilo.

You don't need to run mbr unless you are not able to
boot windows.

Ok, then wait for someone you have more confidence in.

I dont't know anything about the SGD disc but you
don't really need it. You have to change the bootable
flag with any good partitioner(make sure the drive you
change is not mounted) to bootable on hda6 if you want
to boot it and see it in the grub startup menu.

Yes and it will until you remove the bootable flag on
it with some partitioner.

No, that's not how you change which partition it
bootable. it's as I said above.

By all means don't erase your hda2 partition unless
you want to free up that partition for something else.
Just remove the bootable flag on it and it will not
longer be bootable but still can be mounted and
operated upon.

If you haven't received a response from someone else,
I', sure you will shortly but I think they will tell
you the same thing.  Good luck. Hope this helps some.
