INSTALLGRUB 8 "Jan 14, 2015"
NAME
installgrub - install GRUB in a disk partition or a floppy
SYNOPSIS

/sbin/installgrub [-fm] stage1 stage2 raw-device
DESCRIPTION

The installgrub command is an x86-only program. GRUB stands for GRand Unified Bootloader.

installgrub installs GRUB stage 1 and stage 2 files on the boot area of a disk partition. If you specify the -m option, installgrub installs the stage 1 file on the master boot sector of the disk.

OPTIONS

The installgrub command accepts the following options: -f

Suppresses interaction when overwriting the master boot sector.

-m

Installs GRUB stage1 on the master boot sector interactively. You must use this option if Solaris is installed on an extended FDISK or an EFI/GPT partition.

OPERANDS

The installgrub command accepts the following operands: stage1

The name of the GRUB stage 1 file.

stage2

The name of the GRUB stage 2 file.

raw-device

The name of the device onto which GRUB code is to be installed. It must be a character device that is readable and writable. For disk devices, specify the slice where the GRUB menu file is located. (For Solaris it is the root slice.) For a floppy disk, it is /dev/rdiskette.

EXAMPLES

Example 1 Installing GRUB on a Hard Disk Slice

The following command installs GRUB on a system where the root slice is c0d0s0:

example# /sbin/installgrub /boot/grub/stage1 \e
 /boot/grub/stage2 /dev/rdsk/c0d0s0

Example 2 Installing GRUB on a Floppy

The following command installs GRUB on a formatted floppy:

example# mount -F pcfs /dev/diskette /mnt
# mkdir -p /mnt/boot/grub
# cp /boot/grub/* /mnt/boot/grub
# umount /mnt
# cd /boot/grub
# /sbin/installgrub stage1 stage2 /dev/rdiskette
FILES
/boot/grub

Directory where GRUB files reside.

WARNINGS

Installing GRUB on the master boot sector (-m option) overrides any boot manager currently installed on the machine. The system will always boot the GRUB in the Solaris partition regardless of which fdisk partition is active.
