[ubuntu] Making a bootable USB

view story

http://ubuntuforums.org – Well, this is my problem. I have an .iso of MAC OS X that I need to put on my USB to be installed on my macbook. The problem is I cannot find a suitable program that will perform these functions. I have tried Startup Disk Creator but when I select the .iso it does not put it in the .iso field to be put on the USB drive. So if anyone has an idea of how to make a bootable USB containing a MAC OS X .iso using ubuntu 12.04 (My current operating system) I would gladly appreciate it! (Hardware)
