Ventoy is another Multiboot Bootable USB Creation Software Tool that can be used to boot and run multiple ISO files from USB. Its functionality is relatively straight forward. You simply use the utility to format and prepare your thumb drive, then drag and drop your chosen ISO files onto your flash drive. The ISO files are directly copied over and added to the boot menu. This should result in a ready to boot USB device
Much like the YUMI Bootable USB Creator Software, this is an Open Source tool, so everyone is welcome to dig in to see how it works. It supports both legacy BIOS and UEFI boot options, and also works with UEFI Secure Boot.
How it works: This Multiboot USB Tool works by creating a hidden bootable partition which houses the boot menu and GRUB boot loader. While another exFAT partition is created and used for storing the bootable ISO files. This method allows for the storage of file sizes larger than 4GB.
The exFAT partition VT creates on your flash drive can also still be used for traditional storage purposes. This is unlike tools such as Win32 Disk Imager or Etcher that simply use DD to Write an ISO, or Burn ISO to USB. Those tools effectively overwrite the disk content with one single image (creating a USB clone of the source ISO file). Although in some cases (if the disk extents of the source are set properly) you can also create a secondary partition on the device to use for storage.
