Ventoy is an open source tool to create a bootable USB drive for multiple ISO files.
Formatting a USB for every new ISO is a time suck. Ventoy fixes this once and for all: install it once onto a USB drive, then drag‑and‑drop any number of ISOs onto the drive. At boot, you get a menu of all images on the drive — no re‑write needed if you want to add another ISO.
There is a LOT of other features but when it comes to installing ISOs onto bare metal, Ventoy saves a lot of time.
