I guess it is possible to chainload to real cdrom in your drive same way we chainload to windows partition, you can also use script (grub or lua) to determine that your drive is not empty and show chainload menu entry.
Or if you cannot chainload perhaps you could boot this (maybe with memdisk from syslinux) http://btmgr.sourceforge.net/about.html _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
