How to: Dual boot Vista and Leopard on two disks

It is based on the chain0 method. But it doesn't use the boot.ini file.

Since Vista use bcdedit to configure the boot loader. Correct me if I am wrong.


1) Install vista on one disk, Leopard on the other.


In my case, I install Vista first on disk connected to SATA1, then leopard on the disk connected to SATA2.

I didn't unplug the vista disk when I installed Leopard, I just changed the boot sequence in Bios when I need to boot into leopard during the installation. I guess it doesn't matter which OS you install first. I format leopard disk as MBR.

If you want to use GUID, there is a better guide in the forum. For me, I can not get through the leopard installation if I use guid.


2) Set the vista disk at the 1st place of the boot sequence.


I tried to use the leopard boot loader to boot vista. I failed. I hit F8 and I can not see vista( on the other disk ) on the list. Therefore I turned to vista bootloader.


3) boot into vista, insert the Kalyway DVD, copy the "CHAIN0" file to C:\


4) open "command prompt" as administrator.

(The following codes are from)



bcdedit /copy {current} /d “Mac OS X”
bcdedit /enum active
bcdedit /set {GUID} PATH \chain0


Note: In the first command type {current} as it is, literally..nothing else..just {current} with the brackets.

In the 3rd command however, replace the {GUID} with the alphanumeric GUID you see in the enumerated list under MAC OS X.

You can see this list on your terminal as soon as you type the 2nd command above.! As far as i know it is the last entry in the this list.

Also it is same as the one that shows up after the 1st command.! Its the one besides IDENTIFIER not the one besides resume object.!


For Ex: bcdedit /set {38912a-233fdf-45ghghhg-fdfe4} PATH \chain0


5) Dont forget to set


bcdedit /timeout #

Where # is the number of seconds you want the potion to display.


Reboot you should see the list.
