working with Grub2 - PC-BSD Forums

Mahngiel · #1 12-25-2009, 07:23 PM

I'm dual booting Ubuntu and PC-BSD, and grub didn't initially recognize BSD and auto loads Ubuntu.

Going through the knowledge base, i found a doc about working grub from inside linux.

Code:

title PCBSD 0.X (BETA)
root (hd0,1,a)
kernel /boot/loader
boot

However, this is for grub legacy, and not grub 2.

I need help filling this out. PC-BSD is in partition /sda4

Code:

menuentry "PC-BSD" {
        set root=(hd0,4)
	search --no-floppy --fs-uuid --set a24fece6-5e8e-4651-86bf-014295472794
	linux	need this
	initrd	and this
}

thanks.

What I do with Grub2 is to chainlink OpenSolaris and PC-BSD systems with separate files in /etc/grub.d/, my PC-BSD file contains:

Code:

#!/bin/bash

echo "Adding Custom PC-BSD system" >&2
cat << EOF
menuentry "PC-BSD_Unix_KDE" {
        set root=(hd0,2)
	chainloader +1
	boot
			}

EOF

Running 'upgate-grub' on the host system (which happens to be Kubuntu!) loads this into the Grub boot menu.

In my case PC-BSD is on the second primary partition on the hard disk (hd0,2), this file (above) resides in the Kubuntu partition which happens to be a logical one but that's not really relevant. BCD was installed without boot loader.

Hope this helps.
