Ventoy is a free and open source tool to create drives that allow you to select and boot any EFI, IMG, ISO, VHD(x), or WIM files stored on a rewriteable partition on the drive.
Most types of OSs are supported (Windows/WinPE/Linux/ChromeOS/Unix/VMware/Xen...), see the full list.
There are three utilities for setting up the media:
/opt/ventoy/Ventoy2Disk.sh, which is a shell script to be run from the command line.
/opt/ventoy/VentoyGUI.x86_64, which is a graphical application.
xauthor a similar application is needed to escalate to root if the application is not started with root permissions.
file:///opt/ventoy/WebUI/index.htmlwith a web browser.
The same utilities can be used for upgrading the Ventoy installation on the drive.
Ventoy creates two partitions on the drive: one to store the bootable images and another for the Ventoy binaries.
To add images from which you can boot, mount the first partition and copy the images over.

You can afterwards upgrade the drive for future versions by following a similar procedure. Downloading a NEWER-VERSION, verifying the sha256sum, unpacking, running
