Overview of the Ventoy program

 Overview of the Ventoy program

Ventoy is a free and open source bootable flash drive software.


The principle of operation of such applications is as follows: using a special application, we write each ISO image to a USB flash drive, and we do this every time we want to add some new operating system or application to our multiboot flash drive, i.e. we need to constantly use this application.


However, the Ventoy program works a little differently, and this is its main feature: in order to create a multiboot flash drive, we do not need to perform any additional actions with ISO images, we just need to prepare the USB drive once, and then just copy various ISO files on a USB flash drive and moreover, this can be done as many times as you like. Moreover, this flash drive, after it becomes multiboot, you can continue to use, i.e. store regular files on it.


The Ventoy program creates a multi-boot flash drive that will work with both BIOS and UEFI.


You can copy almost any bootable ISO image, it can be both operating systems and various bootable applications.


Ventoy supports many types of OS and a lot of different ISO images have been tested, you can see the full list on the Ventoy program website in a special section - https://ventoy.net/en/isolist.html
