Just transfer the image to the stick (the whole stick, not a partition of it) and it should Just Work. Transfer can be done in Linux by cat, dd, cp or presumably other methods. There is also a Windows utility (win32diskimager) which will copy images to USB sticks. https://www.debian.org/releases/jessie/amd64/ch04s03.html.en There are too many types of failure possible to give a quick guide. Almost always, you will see some kind of error message about a failure. But failure on common modern types of computer are not frequent, in my experience. I have a modern netbook, no legacy BIOS option, UEFI only, Windows 10 already installed. As long as I had enough drive space free, there was no problem with copying to USB stick and installing, with an option for the Win10 boot manager in the grub menu afterwards. -- Joe
