Ventoy is an OS.
It’s a live Linux that boots from the USB stick you format/image with the ventoy tool. The rest of the space on the USB stick is configured to be essentially a standard USB drive.
The live Linux’s sole purpose is to boot another image stored on the USB stick.
So, once you have "ventoy"d a usb stick, you can plonk gparted live iso, Ubuntu, Debian, Eos, W10, W11… whatever isos you want. When you boot from that USB stick, you get the ventoy menu screen and select the iso you want it to continue to boot.
