YUMI – Multiboot USB Creator

YUMI (Your Universal Multiboot Installer) is a USB Boot tool that can be used to make a Multisystem Bootable USB drive. Quickly create a Multiboot USB Flash Drive containing multiple ISO files. Use it to boot your favorite Live Linux Operating Systems, Linux and Windows Installers, antivirus utilities, disc cloning, backup, penetration testing, diagnostic tools, and much more. This tool makes it easy for anyone to create their own customized multi purpose Bootable USB.

YUMI is the recommended successor to our Universal USB Installer and older MultiBoot ISOs tools. Which were amongst the first tools made for the purpose of creating a USB bootable flash drive. Files are generally stored within the Multiboot folder, making for a nicely organized Portable Multiboot USB Drive that can still be used for traditional storage purposes.

Though YUMI was originally intended to be used to store and run various “LIVE Linux” Operating Systems and tools from USB, using it to install Linux from a Flash Drive to a Hard Drive should work with most distributions. If you find a distribution where the installer does not work, please let me know.

YUMI Multiboot Bootable USB Flash Drive Creation

This tool works much like Universal USB Installer, except it can be used to run more than one distribution from your Thumb Drive. Distributions can also be uninstalled using the same tool!

NOTE: A YUMI exFAT variant is still in the works. In the interim, Legacy or UEFI variants are recommended. Here are the key differences:

  • YUMI Legacy supports either NTFS or Fat32 format. BIOS USB boot only.
  • YUMI UEFI supports Fat32 only. BIOS and UEFI USB booting (Distro dependent).

YUMI Legacy (BIOS USB Boot Only)

You can use this version if your computer supports BIOS booting, and if you do not plan to run your Windows installers from YUMI in UEFI mode. Most modern motherboards still have Legacy BIOS firmware support though CMS Legacy mode.

The YUMI UEFI variant utilizes GRUB2 for both UEFI and BIOS booting. Note that this UEFI version is not compatible with the legacy variant. In addition, your USB drive must be Fat32 formatted to support booting in UEFI mode. It utilizes the fat32format utility to format drives larger than 32GB as Fat32.

Drag and Drop ISO Support

The “Try Unlisted ISO” option supports the ability to drag and drop additional ISO files to try into the /multiboot/ISOS folder. They will be autodetected and their entries automatically appended to the Boot Menu.

BACKUP DATA: Backup your content from ALL partitions on your selected USB drive before using the “Wipe and fat32 format” option. The entire disk will be wiped clean!

Diskpart is used to wipe the select drive clean and then create a single partition using the same drive letter. Fat32format is used to format the large partition as fat32.

SECURE BOOTING: If it is enabled, you will need to disable secure boot from your computers BIOS/UEFI system firmware menu, before booting.

Running YUMI from LINUX: WINE is NOT currently working. 

YUMI Basic Essentials

NOTE: For legacy YUMI, your USB drive must be Fat32/NTFS formatted, otherwise Syslinux will fail and as a result, your drive will NOT Boot. NTFS may not work with every distribution but is required for storing files over 4GB. YUMI UEFI currently must use Fat32 format.

YUMI Legacy or UEFI can be used to format your select USB drive, but be aware that all partitions on the select disk will also be deleted. Ensure that you have made a backup of any information you want to keep before using YUMI on any drive.

Basic Essentials to create a Multi System Bootable USB Drive

Recommended: You’ll have the best experience when using YUMI on a Fast SSD Flash Drive. Here’s a list of recommended Fast Flash Drives.

  • 2GB+ Fat32 or *NTFS Formatted USB Flash Drive.
  • Computer that can boot from USB.
  • Windows 11, 10, 8, 7 Operating Environment.
  • YUMI (to create a Multiboot Bootable USB).
  • Your favorite ISO Files.

Please inform me of unlisted “FREE” Live Linux distributions or version revisions, and I will attempt to update YUMI to support them. Additionally, developers who wish to have their Live Linux distribution added, can direct me to a copy to try.
