Ventoy
A New Bootable USB Solution


Ventoy: create bootable USB media that uses ISO images
by Martin Brinkmann on April 20, 2020 in Software - No comments

When you want to create a bootable USB device, you may use programs like Rufus for that or tools provided by the developers of operating systems. What these tools do, usually, is to extract an ISO image to the USB device and make the device bootable in the process.

Ventoy is a new software application for Linux and Windows that does things a bit differently. Instead of extracting an ISO image, it allows you to place the actual ISO images on the USB device so that you may boot from them directly. The program supports multiple ISO images that you can place on a USB device and uses GRUB as the boot manager.

You can transfer multiple ISO images to the device once the Ventoy structure has been created on the device using an installer. It is possible to place Windows and Linux images on the device to boot from them whenever the need arises. Updating of ISO images is a breeze as well as you simply replace an ISO image with another.

Related booting live iso from disks - other methods;
for Linux you can boot iso of "Any distribution that ships with a Loopback.cfg" with SuperGrub2Disk and even from the HDD with this method; https://eawonlinux.neocities.org/eollinux-quicktut1.html Specifically it addresses how to use a bootable DVD (or CD) iso to install (from a second drive) when you have no DVD (or CD). Or it can just boot a live iso from the primary but you would NOT be able to install it - see the notes.

also rEFInd , see: https://eawonlinux.neocities.org/eolrefind.html is a boot manager that can select any bootable iso (its something you would install replacing a Windows or Linux boot manager )
