The biggest downside to this program is the one that ultimately matters least and that's its appearance. That lets you dedicate enough room for your rescue disks, cleaning utilities, and other software you might need in a computer emergency. The utility can format your drive as it installs or leave parts of the drive untouched. That means every power user will get the exact build they want on their thumb drive without much work. If you don't have the ISO files downloaded, this tool will go search them out for you. If for some reason you can't find the build you want, YUMI lets you try to install a different, unlisted build. When you're setting it up, it lets you choose multiple Windows builds in addition to just about every popular Linux installation, including Debian, Fedora, Ubuntu, and more. If you need to rescue an old or infected PC, this program will be the hero you want.

Not only does it let you hold multiple operating systems, but also it lets you install anti-virus and performance-boosting utilities. YUMI isn't much to look at, but performs as an incredibly powerful tool for creating bootable USB drives.
