Goal: Create bootable USB stick that allows booting from multiple OS images (and still provides scratch storage).
Prep: This was done successfully using a 32GB version of this USB stick (Costco ~~$20 for a two-pack)
Source: Ventoy: Get Started
For Linux - CLI mode
the USB drive will be formatted and all the data will be lost after install
Install Ventoy once, after that all that is needed is to copy the iso files to the USB
Download the installation package, like ventoy-x.x.xx-linux.tar.gz and decompress it.
Run the shell script as root
sh Ventoy2Disk.sh { -i | -I | -u } /dev/XXX
