jefro: Thanks for the quick reply and the welcome. It was nearly a month ago when I extracted the ISO from Debian, but clicking on your provided link, did lead me to this page:
https://www.debian.org/distrib
There, it gives a clear option for (either) downloading image or try Debian live. I did not see this page; I clicked on the "Download Debian 9.1" directly from the right-side-top banner of its home page:
https://www.debian.org

IsaacKuo: Thanks also! Since I do not want to download it yet until I can play with it for awhile, I am going to try as you suggested, and keep Mint 18.2 Sonya my primary (SSD) Distro for a bit longer. So if you do not mind, and knowing what I'm working with now (equipment, programs, etc), care to offer a quick how-to? Other future seekers who keyword search and land here, would also appreciate the conversation (the assurance mostly, for us Linux newbies).
