In short, GRUB will install and it can handle many
OSes. Whether the OSes behave is another issue with
NT/XP/2K all complaining bitterly if you move them to
another partition.
And since 10.0 is not a download, the book that comes
with it shows the install routine. If not, well, you
get to trudge forward and know that while multibooting
is done all over, no one will really offer you much
more than "it should work" support.
