Ventoy lets you put multiple ISOs on one USB drive and pick which to boot from a menu. This is ideal when you only have one USB — you can have both CachyOS live ISO and Windows LTSC ISO on it.
⚠️ Warning: Installing Ventoy will wipe the USB drive. If you previously flashed CachyOS withdd, you'll re-add it as a file afterward.
