Karmic Koala, back into legacy GRUB

One of  a lot of new feature of Ubuntu Karmic Koala (9.10) is GRUB2 (GRand Unified Bootloader 2).  GRUB2 has replaced formerly known GRUB-Legacy (0.9x), which no longer being developed. It has significant different comparing with previous version, there is no longer /boot/grub/menu.lst  file, GRUB2 boot menu handled by /boot/grub/grub.cfg. This file automatically generated when system boot. but how if we still want to use old stuff, For example, i didn’t succeed to configure this newest version for pc_efi boot, meanwhile i need this for dual booting with my OSX86.
First, we need to remove this GRUB2 version

sudo apt-get --purge remove grub*

Remove all files from latest installation

sudo rm -rf /boot/grub/*

Now, installing GRUB legacy

sudo apt-get install grub

Then, we have to generate menu.lst file, which needed for booting

sudo update-grub

You can configure menu.lst file as you needed, and installing to system with this command,

sudo grub 

Find where your linux root partision located with :

find /boot/grub/stage1

Set root partition with result of command above, i my case (hd0,4)

root (hd0,4)

Install into MBR, normally hd0, maybe different in your machine

setup (hd0)

Bingo, now your GRUB back to legacy.

    that’s weird. I could both configure grub2 to work with my PC_EFI and it also automagically identified my osx86 installed (kalyway) and when I boot through that it even can see my 2 processors, while through EFI it can’t.

    I was hoping it would also fix my sound or airport, but that didn’t happen.

    Anyway, here’s my EFI configuration on grub2 in case you want to try it:

    menuentry “Mac OSX (bootloader)” {
    set root=(hd0,8) #this is my ubuntu partition
    multiboot /boot/boot_v8
