Ultimate Boot CD

I found another way. https://youtu.be/BPOxSrEgfV4 - He explains it better.

CREATING a bootable USB.
1. IOS easy !
2. "burning" ??? How is that different than copying ?
3. Can't boot till I have one made.
4. Easy, I've used the CD before.

Thank you for the reply.

I went through several tutorials and none of them were useful. They contained a LOT of Bad/Outdated links. Does anyone have another step by step process to do this ?
Your written instructions or a YouTube video would be very helpful. - Thank you !
