grub2 and osx86

[congomonster]

Hi,

need some help don't get it to work.
My configuration

Windows 7
Data Drive
Ubuntu 10.04 beta all on the first partition

mac os x on second HDD

How can i get grub 2 to boot into chameleon ?

i have tried to make some entry's in the grub.cfg but nothing helped. Most i get a could not open file. How can i verify i have chameleon installed right ?

Quite simple:

- Copy "boot" (from chameleon) to /boot/grub
- add to grub.cfg: "multiboot /boot/grub/boot" (without quotes)

My OS X-Partition is recognized by grub automatically. It adds the
OS X to grub.cfg. This config boots my hack, but it definitly slower than the
above method (tested with geekbench).

Good luck

Thanks but that makes the pc only reboot and reboot

Ok, here is my solution:

Your Grub2 recognized your OS X, and you have an boot option for OS X... right?

ok...
Ubuntu:
1.) Install MC with synaptic
2.) Open a terminal and run mc

sudo mc

3.) search in mc

/boot/grub/grub.cfg

4.) Press ‹f4› to edit
5.) search your OS X's menu entry
6.) edit your entry to look like this:

menuentry "Mac OS X" {
        insmod hfsplus
        search --file --set=root /boot
        multiboot /boot
}

These steps not needed, just for look nice your boot:
7.) boot your mac and if you want edit your com.apple.boot.plist using plist (offcourse as root*) editor
8.) remove any timeout, and instant menu entry (if you have any)
9.) put this

Quiet Boot = Yes

That's it... Enjoy your silent booting OS X from Grub2

(1) Copy chain0 to the root partition of your snow leopard installation.(Extract from a snow leopard installation dvd)

(2) Add this entry to your 40_custom file in grub.d. (\etc\default\grub.d)

menuentry "SNOW LEOPARD" {
insmod hfsplus
set root=(hdx,y)
parttool (hdx,y) boot+
chainloader /chain0
}

(Change x and y to match your snow leopard disk and partition)

(3) Run sudo update-grub from a terminal in whichever os you installed grub from. (Ubuntu 10.4 in my case)

I cannot remember where I found this information, but the credit goes to them if this works for you as it did for me.
