So, what do I have to do to get my Mac to recognize and boot from another OS on a USB flash drive? I am not sure if there is any specific property of the drive or any specific file that can help me uniquely identify the internal boot drive. I have had the same issue trying to use the Ultimate Boot CD on a USB, various Live USBs for Linux, etc. I need to determine inside my app which of the internal drives in my Mac is the boot drive.

Since the installer file is bigger than 4GB, we'll be using two separate commands to create the bootable disk.
