How to upgrade from ubuntu MATE 16.04 to 17.10?

I have the ubuntu MATE 17.10 ISO on DVD, but am not able to make it to a working program. I need help to make a working stick to install the 17.10.

My go to app is etcher

another great and simple app is ROSA

ROSA ImageWriter - Rosalab Wiki

BUT etcher is in the Software Boutique and is cross platform
