The installation of Windows, Linux, or Mac operating system has been automated and foolproof for a long time, with no technical difficulty. But if you want to install and use multiple systems at the same time, whether it's a combination of multiple different versions of Windows or Windows + Linux + Mac (each has a different boot method), the hardest part is figuring out their installation order and adjusting the boot menu. This can be cumbersome and experience required even for advanced computer users.

YUMI (short for Your Universal Multiboot Installer) is the successor of MultibootISOs, a free, open-source, powerful and user-friendly USB installer maker. It is used to create multi-system bootable USB devices, which can boot multiple operating systems, antivirus programs, disk cloning tools, system diagnostic tools, and more.
