It should work- if there are no other errors. I think grub-install failed
for some reason.

I prefer setting up from within the "grub shell," as opposed to
grub-install. From the interactive shell, you can see if there are any
problems with the setup.

$grub
        grub>root (hd0,1)
        grub>setup (hd0)
        grub>quit

Watch for error messages after each command.

Notice the command root (hd0,1) specifies where menu.lst and the rest of
grub is located, not the root filesystem.
