boot from Leopard iso with linux Grub

[othman]

Hi guys,

I have an iso file for Mac leopard which is about 8GB size. I couldn't burn it to a normal dvd b/c standard dvd size is about 5GB.

I was wondering if there is a method to use Linux Grub bootloader to boot from this 8GB iso file ?

currently i'm using Grub for a triple boot (windows/linux/mac os x tiger ).

can someone describe me in details the steps i should perform to boot from this ISO in order to install the Leopard Intel in my machine?

either using grub or any other method description would be very welcome.

thanks

From the Tiger install try mounting the ISO then in a Terminal window open the installer from the mounted disk to proceed with the install.

 

 cd /Volumes/Mac\ OS\ X\ Install\ DVD/System/Installation/Packages
open OSInstall.mpkg
/usr/sbin/vsdbutil -a /Volumes/Your_Install_Partitions_Name
cd

 

The first command changes into the mounted disk the second opens the installer where you proceed with your install the third takes ownership of the installed to disk back so you can put your patches needed for your machine onto it the fourth gets back out of the mounted install disk so you can unmount it. If you need more than this to get it working then we would need to know the hardware in the machine and how/where you are going to install/boot the machine.

thanks for helpful reply.

in fact i have the .dmg file of Leaopard 8GB.both Leopard dmg & iso -which was generated from dmg using PowerISO tool- are now in my windows partition. i have a couple of questions:

1-do i need to move the 8GB .dmg to my tiger partition or leave it in windows partition?

2-How can i mount the .dmg file from my tiger installation ? do i have to use diskutility ?or use a unix command line ?

3-can you explain me in more depth the first 2 commands in your reply ? i'm curious to know what they are doing exactly?

thanks.

I used diskutil to make the .dmg I used but that would probably work as well.

1-do i need to move the 8GB .dmg to my tiger partition or leave it in windows partition?

 

Probably should be on the Tiger partition just to ensure the proper permissions/access to it I doubt a windows partition is going to do that correctly.

2-How can i mount the .dmg file from my tiger installation ? do i have to use diskutility ?or use a unix command line ?

 

Double clicking or right click and Open always uses DiskImageMounter to do it here.

Not much to explain really the first command changes (cd = change directory) you to the directory containing the stand alone installer package the second opens it (runs the program/package) allowing you to go through an install without having to reboot using the actual install DVD like you normally would on a Mac to install the system, your welcome.

thank you much.

I will try your method & let you know if it works with me.

i have a small question :

for command :

/usr/sbin/vsdbutil -a /Volumes/Your_Install_Partitions_Name

in fact i want to replace my tiger installation with the leopard one. my tiger partition is sda1 , windows is sda3 and i have another 10 GB FAT32 partition that is sda2 .what should i use as "Your_Install_Partitions_Name" ? should it be a blank partition that i need to create ? can i run the leopard installer from my tiger partition and in same time install leopard over current tiger partition ?

 

thanks for further help.

"Your_Install_Partitions_Name" is what you named your install partition in diskutil when creating the blank hfs+ formatted partition for install. You cannot install over a live running system this is true in all OS's as far as I know. This idea here would best be tried on an external USB bootable drive first then you can take and use diskutil to clone it back to the internal drive while running from the USB drive. Now I see you only have the one disk here it would be better if you put in another drive for only the OS X as this will allow you to partition GUID format HFS+ just lke a real Mac would be. Otherwise you need to figure out the boot loader plus installing onto a MBR partitioned hard drive.
