Ventoy

usb iso boot program

Ventoy is an open source tool for creating a bootable USB drive for ISO files. With Ventoy, you don't have to format the disc repeatedly, just copy the iso file to the USB drive and boot it.

You can copy many iso files at the same time, and ventoy will give a boot menu to select them (screenshot). Both Legacy BIOS and UEFI are supported in the same way. More than 200 ISO files are tested (list).

Ventoy offers a "Ventoy Compatible" concept that can help support any ISO file.
