Through my epic research, I found great information that I want to share with all of you.  Last year I unsuccessfully tried to find information on how to boot my iBook G4 from a USB.  If you have a PowerPC (most models) it won’t boot from a USB but I found a Ben Collins’ blog that teaches you how to do it, step by step.  Just follow the info in this link, and I know you will find the answer to your prayers!
