howto multiboot linux + OSX (on usb drive)

Silver Byte · December 4, 2008

hi guys,

I have been reading a lot of stuff about installing OSX on my laptop recently. I need Leopard only for XCode.

At first I used Kalway 10.5.2 on my laptop HDD which it promptly killed (MBR gone), so now I definitely need it to be on an external USB drive only.

Then I came across another simple guide (http://linux-guider.blogspot.com/2008/09/i...54-is-easy.html), which is why I downloaded iATKOS 5i. I installed it to the USB drive, but it doesnt boot , so I made a mistake there.

So, here are my questions to you gurus:

My steps are: 1. format USB drive as HFS+ journaled partition.

2. Open Terminal. Do "fdisk -e /dev/rdisk2s1". Then "flag 0".

3. Select 9.2 kernel

4. Install to USB drive partition.

Now I see discussions about the linux menu.lst entries

Some say

Title OS X
Root (hd0,2)

make active

chainloader +1

title Mac OSX Leopard
root (hd0,0)

kernel /boot/boot_v8

boot

Third person mentions creating a ext3 partition on the HFS disk and storing the boot_v8 there(http://forum.insanelymac.com/lofiversion/i...p:/t128857.html).

Yet others mention they enabled USB drive booting by Chameleon EFI bootloader.

I have killed my primary OS three times till now, so could someone help me by pointing out the correct approach. I'm at a loss here.

thanks...
