Usage: grub-install [OPTION] install_device
Install GRUB on your drive.
-h, --help print this message and exit
-v, --version print the version information and exit
--modules=MODULES pre-load specified modules MODULES
--root-directory=DIR install GRUB images under the directory DIR
instead of the root directory
--grub-setup=FILE use FILE as grub-setup
--grub-mkimage=FILE use FILE as grub-mkimage
--grub-mkdevicemap=FILE use FILE as grub-mkdevicemap
--grub-probe=FILE use FILE as grub-probe
--no-floppy do not probe any floppy drive
--recheck probe a device map even if it already exists
INSTALL_DEVICE can be a GRUB device name or a system device filename.
grub-install copies GRUB images into the DIR/boot directory specified by
--root-directory, and uses grub-setup to install grub into the boot
sector.
