Set up the installation of GRUB automatically. This command uses the more flexible command install (see install) in the backend and installs GRUB into the device install_device. If image_device is specified, then find the GRUB images (see Images) in the device image_device, otherwise use the current root device, which can be set by the command root. If install_device is a hard disk, then embed a Stage 1.5 in the disk if possible.

The option --prefix specifies the directory under which GRUB images are put. If it is not specified, GRUB automatically searches them in /boot/grub and /grub.

The options --force-lba and --stage2 are just passed to install if specified. See install, for more information.
