It does not really depend on a given OS, but it does need to know
where its files are. When you wipe out /boot, you usually wipe out
the files Grub needs. (The menu and stage 2.) Now, there files do
not have to be stored on a Linux file system. You could store them
on a separate file system. I know there is a stage 1.5 for FAT file
systems, but I don't think there is one for NTFS. (I could be wrong

It is fairly simple to add a Grub menu entry for that. You just add
vga=<mode> or vga=ask to a normal menu entry.

Right now, you can hit any key to get to the menu in Grub when you
see the booting message. The delay is configurable, or you can have
it always show you then menu. You can have the menu entries titled
what ever you want. In the long run, you are probably going to want
to modify the template used to generate /boot/grub/grub.conf when
you add a new kernel, but I don't remember what file it is offhand.
