 Ventoy is an open source tool to create bootable USB drive for ISO/WIM/IMG/VHD(x)/EFI files. <br/>
 With ventoy, you don't need to format the disk over and over, you just need to copy the image files to the USB drive and boot it.   
-You can copy many iso files at a time and ventoy will give you a boot menu to select them. <br/> 
-Both Legacy BIOS and UEFI are supported in the same way.<br/>
