Usage: grub-install [OPTION] install_device
62
Install GRUB on your drive.
64
-h, --help print this message and exit
65
-v, --version print the version information and exit
66
--root-directory=DIR install GRUB images under the directory DIR
67
instead of the root directory
68
--grub-shell=FILE use FILE as the grub shell
69
--no-floppy do not probe any floppy drive
70
--force-lba force GRUB to use LBA mode even for a buggy
72
--recheck probe a device map even if it already exists
74
INSTALL_DEVICE can be a GRUB device name or a system device filename.
76
grub-install copies GRUB images into the DIR/boot directory specfied by
77
--root-directory, and uses the grub shell to install grub into the boot
80
Report bugs to <bug-grub@gnu.org>.
