Ventoy is an open source tool to create bootable USB drive for ISO/WIM/IMG/VHD(x)/EFI files.
With Ventoy, you don't need to format the disk over and over, just drag-and-drop files to the USB drive and boot them directly.
You can copy many files to different folders and Ventoy will give you a boot menu to select them (screenshot).
You can also browse ISO/WIM/IMG/VHD(x)/EFI files in local disks and directly boot them.
x86 Legacy BIOS, IA32 UEFI, x86_64 UEFI, ARM64 UEFI and MIPS64EL UEFI are supported in the same way.
Most types of OS supported

Ventoy is a free and open-source tool that can turn any USB into a multiboot device. Once configured, you can drag and drop ISO files onto the drive, and all of them will be available via a boot menu. More importantly, you can continue to use your USB drive as a regular media storage device.
