Details:
I have amd64 computer which is obviously BIOS-based system, then mine boot
harddisk is GPT-type. All works well with this so far, but I also have
secondary HD that is MBR/msdos type, which has Windows in there.
30_osprober script finds the drive/partitions and generates nice menuitem for
it, but grub throws error about couldn't find uuid xxxxxxxx, thus not working
menuitem.
ls -l at grub commandline shows there is hd1 but like it would contain
nothing.
Solution is to add "GRUB_PRELOAD_MODULES=part_msdos" into /etc/grub/default
so grub will load that module at boot time, which in turn will make the
secondary msdos-type disc usable again.
Maybe this "GPT-bootdisc in BIOS-computer" is rather rare configuration, but
nevertheless would be great if this type of feature would work "out of box"
