Hi So, I understand nativedisk or installing grub with --disk-module=native will bypass BIOS and have grub access the hardware using its own drivers, which I won't have to insert with insmod commands.

My PC is a BIOS plateforme. env LANG=all sudo grub-install -V grub-install (GRUB) 2.02~beta2-9ubuntu1.4 I got a program error : env LANG=all sudo grub-install --boot-directory=/mnt/boot --disk-module=native /dev/sdd grub-install: --disk-module: (PROGRAM ERROR) Option should have been recognized!? Try 'grub-install --help' or 'grub-install --usage' for more information. > > > > _______________________________________________ > Help-grub mailing list > [email protected] > https://lists.gnu.org/mailman/listinfo/help-grub
