Probably want to skip that "--root-directory" option, unless you're trying to avoid the mbr for some valid reason...
I've tried it with and without.
Might want to stick with genuine Debian documentation, too, unless you're actually running Ubuntu...
I've had trouble finding much Grub2 documentation. http://wiki.debian.org/Grub2 is a bit sparse & the GRUB site recommends the Ubuntu documentation http://www.gnu.org/software/grub/grub-documentation.htmlinfo grub does produce more & I'm trying to find the relevant bit at the moment.
Thanks. Bob
