The root (hd0,0) is only used by Grub, and tells Grub where to find
its information. It is completely independent of the OS. But it does
need to be on a file system that Grub can read. (There are
exceptions to this...) The only affect it has on booting Linux is
that it tells Grub the start of the path to find the files specified
in the menu entries. It has nothing to do with locating grub.conf.
This is set by grub-install.

As for Grub documentation, you can try the Grub info file. It can be
a bit cryptic in places, but it does cover this. The thing to
remember is that Grub is not a Linux program. It is a boot loader
that can load Linux, as well as other operating systems. You can
install and use Grub on a system that does not have Linux installed
at all. You can also boot a Linux system that does not have Grub
installed.
