16. Invoking grub-install
The program grub-install
installs GRUB on your drive using the
grub shell (see section 15. Invoking the grub shell). You must specify the
device name on which you want to install GRUB, like this:
| grub-install install_device
|
The device name install_device is an OS device name or a GRUB
device name.
grub-install
accepts the following options:
- `--help'
- Print a summary of the command-line options and exit.
- `--version'
- Print the version number of GRUB and exit.
- `--force-lba'
- Force GRUB to use LBA mode even for a buggy BIOS. Use this option only
if your BIOS doesn't work properly in LBA mode even though it supports
LBA mode.
- `--root-directory=dir'
- Install GRUB images under the directory dir instead of the root
directory. This option is useful when you want to install GRUB into a
separate partition or a removable disk. Here is an example in which
you have a separate boot partition which is mounted on
`/boot':
| grub-install --root-directory=/boot hd0
|
- `--grub-shell=file'
- Use file as the grub shell. You can append arbitrary options to
file after the file name, like this:
| grub-install --grub-shell="grub --read-only" /dev/fd0
|
- `--recheck'
- Recheck the device map, even if `/boot/grub/device.map' already
exists. You should use this option whenever you add/remove a disk
into/from your computer.
