How to easily create a bootable flash drive using Ventoy

Ventoy is a fairly new open source tool for creating bootable USB drives using Linux or Microsoft Windows ISO files.

You install this tool on a USB stick, then just copy the ISO images to the USB stick and you can boot from it without any other changes (so there is no need to reformat the USB stick every time you want to create a bootable USB stick, and without having to extract the contents of the ISO file).
