grub-bios-setup (GRUB) 2.02~beta2-36ubuntu3.7

Usage: grub-bios-setup [OPTION...] DEVICE Set up images to boot from DEVICE. You should not normally run this program directly. Use grub-install instead. -a, --allow-floppy make the drive also bootable as floppy (default for fdX devices). May break on some BIOSes. -b, --boot-image=FILE use FILE as the boot image [default=boot.img] -c, --core-image=FILE use FILE as the core image [default=core.img] -d, --directory=DIR use GRUB files in the directory DIR [default=/boot/grub] -f, --force install even if problems are detected -m, --device-map=FILE use FILE as the device map [default=/boot/grub/device.map] --no-rs-codes Do not apply any reed-solomon codes when embedding core.img. This option is only available on x86 BIOS targets. -s, --skip-fs-probe do not probe for filesystems in DEVICE -v, --verbose print verbose messages. -?, --help give this help list --usage give a short usage message -V, --version print program version Mandatory or optional arguments to long options are also mandatory or optional for any corresponding short options. DEVICE must be an OS device (e.g. /dev/sda). Report bugs to <bug-grub@gnu.org>.
