The Ventoy application installs the files needed for a bootable USB by creating a stick that will start your computer.
But the good stuff comes after installing the Ventoy bootable files on the USB. The right shaped free space of USB can accept with simple copy-paste, as many ISOs as you want, Windows, or Linux.
The USB with the Ventoy bootable files will boot and show you a boot menu to select the operating system you want.
According to the official website, it has been tested and works with over 700 ISO files. I personally tried it by creating a USB that contained 2 different Windows (10 and 11)
It is very simple to use, and supports Legacy and UEFI boot menus.
Download the app for platform you are interested.
I tried the application on a Linux system (it has CLI and GUI options) and I was very happy with the result. I imagine the Windows application will be no different.
Open the application, Select from "Options" if you need Secure Boot, put your USB in a port that your computer. If the application does not "see" it, click on refresh.
