(8)GRUB-SETUP - Set up images to boot from a given device.

SYNOPSIS

grub-setup [OPTION]... DEVICE

DESCRIPTION

grub-setup is the tool that will actually copy boot.img and core.img to the boot drive. This tool is usually invoked by (8)grub-install.

If the destination device can have partitions and it is the MBR, grub-setup will try to embed the core image into after the MBR (that's compulsory when root is on RAID or LVM). Otherwise, the core.img will be copied to filesystem.

This command is only useful (and available) on plain PC (not on EFI, or Open Firmware based systems).

-b FILE, --boot-image=FILE

Use FILE as the boot image [default=/boot/grub/boot.img].

-c FILE, --core-image=FILE

Use FILE as the core image [default=/boot/grub/core.img]

-d DIR, --directory=DIR

Use GRUB files in the directory DIR [default=/boot/grub/]

-m FILE, --devicemap=FILE

Use FILE as the device map [default=/boot/grub/device.map]

-h, --help

Print this message and exit.

-v, --version

Print the version information and exit

-r DEV, --root-device=DEV

Use DEV as the root device [default=guessed].
