What is ventoy
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, you just need to copy the ISO/WIM/IMG/VHD(x)/EFI files to the USB drive and boot them directly.
• You can copy many files at a time and ventoy will give you a boot menu to select them (screenshot).
• x86 Legacy BIOS, IA32 UEFI, x86_64 UEFI, ARM64 UEFI and MIPS64EL UEFI are supported in the same way.
• Most type of OS supported (Windows/WinPE/Linux/ChromeOS/Unix/VMware/Xen…)

This can be loaded on to a USB disk instead of a flash drive for a potential better overall experience.
