How to create a Bootable Pendrive from Retail Leopard *.dmg file?

[antisocialbratt]

Hi everyone, I wanna know how to create a bootable usb pen drive from the Retail version of Mac Leopard 10.5.5. which is 7.3 gb. Problem is that i have this file in *.dmg format and i wanna create a usb bootable pen drive in windows xp or vista. I know there has to be a way, as creating a bootable pen drive is possible. I created Windows Vista Bootable pen drive using UltraISO. The pen drive works and installation takes a lot less time. Now many of you would say that Ultra ISO has Dmg support. Well i agree, it has, it reads the dmg file of mac leo and shows its contents. But when i try to create a usb bootable pendrive with exactly the same method i used for ISO image of Windows Vista, i get an Access Violation Error. I Tried converting the dmg to iso in ultraISO,but the resultant ISO file isnt bootable. So can someone help me.

 

Either tell me how to Create a bootable USB pendrive in windows xp or vista.

Or tell me how to edit the 7.3 gb retail file in windows xp or vista so that it would be reduced enough to fit in a Single layer DVD (as i have wasted 3 4$ DL discs while trying to burn this using Transmac)
