Ventoy is one program open source that creates bootable USB flash drives using ISO images.
The Ventoy is a free program, open source, equivalent to Rufus. That is, it can create bootable USB flash drives (or dvds, or SD, or SSD) with the operating system of your choice. The difference with Rufus is that it flashes the ISO image of the operating proletterand does not export it.
Even better, it is possible to insert multiple ISO images into the USB device after it has been prepared by Ventoy. This allows you to boot into different Linux systems or install different versions of Windows directly from a single USB device.

The program has support for Secure Boot, for ISO/WIM/IMG/VHD(x)/EFI type images, to change the file system of the first partition (FAT32 / exFAT / ntfs / udf / xfs / ext2 / ext3 / ext4).
