ISO tutorials

been looking for a tutorial on how to make ISO's.
tried to burn a disc (copy) and received the message illegal,can't copy *****',does anyone know of a tutorial on ISO,s or a way I can get around this?

Not sure what you're trying to do but this works for
me . A free program "rawrite**".
Simply start program under a dos prompt and enter
path-to-file you're using.
At dos prompt;
"rawrite** path-to-your-file :a"

"a" represents where you are writing it to.
