When you want to boot an ISO with the same USB drive, just copy the ISO file (or multiple ISOs) to the USB and boot from it. Delete all ISO files from it and use it as a regular USB drive (Ventoy only takes up a few MB of space and is not visible when the USB drive is installed). In order to use the entire USB drive for other purposes, you do not have to format it.

After installing Ventoy on the USB drive, you can use the USB drive to start the ISO file copied to the USB drive, but you can also copy other files to the USB drive, which will not affect the operation of Ventoy. It is worth noting that you can continue to use the USB memory stick for other purposes. You can even create a multi-boot USB drive by adding ISO files for certain Linux distributions and Windows ISO files on the same USB, as shown in the screenshot at the top of this page. When copying multiple ISO files to a USB drive, Ventoy will provide a menu at startup, from which you can select the ISO to boot. It only has a graphical user interface on Windows on Linux, you need to use it from the command line. The application is available for Microsoft Windows and Linux.
