Ventoy is a new free portable bootable UFD solution for managing multiple disk images and creating a multi-boot UFD. Once you have created your Ventoy UFD, you simply copy your ISO disk images there and when you boot the Ventoy UFD, you are presented with a menu of all your disk images. Check out all the screenshots of various different boot images booting here. And it can support both UEFI and Legacy BIOS at the same time. The way it works is it creates two partitions on your UFD. Here is a before and after of the MBR partitons on your UFD. You can change it to GPT if you like. You can easily update Ventoy by clicking the Update button. It also supports various Plugins. By default, the 1st partition is formatted with exFAT file system, but you can also reformat it manually to NTFS/FAT32/UDF/XFS/Ext2/3/4. That is the partition that you will see in your file manager and where you copy and manage your disk images. The other partition is an EFI System Partition which runs Ventoy. This is my Ventoy UFD. To some degree, I am thinking that Ventoy resembles TeraByte BootIt UEFI. I think it will be a very handy backup tool.
