Use it to boot from USB your favorite Live Linux distributions, Windows setup installers, antivirus utilities, disc cloning, backup software, penetration testing utilities, diagnostic tools, and much more. Making it easy for anyone to create their own customized multi purpose bootable USB.

What is YUMI Multiboot?

YUMI is a media creation tool has been considered by many to be the best bootable USB Creator. It replaces our old Multiboot ISOS tool and is also the successor to the Universal USB Installer (UUI). Tools that were among the first ever made for the purpose of creating a bootable flash drive.

In general and for the most part, bootable ISO files are stored within the YUMI folder. This makes for a nicely organized portable Multiboot drive that can still be used for traditional storage purposes. Though originally intended to be used to boot from USB “LIVE Linux” Operating Systems and tools, using it to install Linux from a flash drive to a hard drive should also work fine with most distributions. If you do happen to find a distro where the installer does not work, please let me know. You can also use the software to create USB bootable Windows setup installers, enabling you to easily install Windows 10 from USB.

Multiboot Bootable USB Flash Drive Creation

This Multiboot USB maker can be used to store and run more than one distribution from your thumb drive. Enabling you to boot Multiple ISO files from the same device. Distributions can also easily be uninstalled or removed with the tool!

You might be asking, How can I boot from USB with exFAT? For that, the specific YUMI exFAT variant was created. This Windows based media creation tool can be used to automatically create an exFAT bootable USB. It supports the exFAT format, can hold 4GB+ ISO files, allows up to 40GB persistence storage, along with the ability to BIOS and UEFI USB boot.

Supports both BIOS and UEFI USB Boot: YUMI allows you to keep using an exFAT format on your USB drive and store files larger than 4GB. Both modern UEFI and Legacy BIOS boot modes are supported. You can also optionally drag and drop bootable ISO files into folders onto your flash drive to be automatically detected and added to the boot menu at startup.

The exFAT variant utilizes a bootloader based on Ventoy2Disk along with a custom theme and configuration enabling you to use advanced Ventoy boot methods with YUMI’s helpful front end. Making it easy to discover and learn more about new distributions to download and try. Create, and manage for example; Debian and Ubuntu based distributions with persistent images, or make multiple Windows Media Installers. You can even use this software for fully installing Windows onto USB in which case each distribution is stored and booted from separate VHDx images.

It is important to note that this variant is also backwards compatible with Ventoy. In fact, if you’d like, instead of using YUMI2USB you can copy YUMI-exFAT- to the same location as your Ventoy2Disk.exe and the multiboot USB boot tool will autodetect and use Ventoy instead for performing installation/updates.

How the YUMI app works

Once the drive has been prepared, you can use the front end Installer to learn more about and download distributions and tools to put on a select drive. The front end will create an organized folder structure and copy each ISO to the drive for you (handy if you want the media creation tool to keep track of your installations for removal). It can also create persistent storage files for you along with related .json entries. Each Arch, Fedora, Debian or Ubuntu based distribution can have its own persistent storage.

YUMI Features:

  • Official Website links are provided to help you learn more about each USB bootable distribution.
  • Download links make it easy to find new ISO files to try on your bootable USB.
  • Up to 40GB persistence file creation for Arch, Fedora, Ubuntu and Debian based distributions such as KALI Linux.
  • Easily add or remove installed ISO distributions.
  • Automatic drive preparation using a Fat32 boot partition and exFAT partition for storage.
  • Optional ability to “Drag and Drop ISO files” onto USB.
  • 100% Free and Open Source (version specific source code is provided upon release).

Side Note: You can also create your own storage folders within the YUMI folder on the flash drive and then just drag and drop your ISO, IMG, WIM, VHD(x), VDI.vtoy, and EFI files into those folders. During startup, the system will add entries for discovered items. Stored files can be larger than 4GB.

Essentials to create a multi system bootable USB drive

This USB Boot Installer will format your select drive with one exFAT and one Fat32 partition, but be aware that all existing partitions on the select disk will be deleted. You’ll want to ensure that you have made a backup of any data you want to keep before using YUMI software on any drive.

Recommended: You will have the best experience when using a fast SSD flash drive. Here is a list of suggested Best Fast Flash Drives.

  • 8GB+ flash drive (128GB – 1TB size works well).
  • Computer that can boot from USB.
  • Windows 11, 10, 8, 7 Operating Environment.
  • YUMI (to create a Multiboot Bootable USB).
  • Your favorite Windows and Linux ISO Files.

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

How to Create a MultiBoot USB Flash Drive (Windows)
  1. Run* YUMI following the onscreen instructions.
  2. Then, Run the tool again to Add More ISOs/Distributions to your Drive.
  3. Restart your PC. But be sure to set your Boot Menu to boot from USB.
  4. Select a distribution to launch. Then, boot and enjoy!
Booting from a USB Flash Drive

Here are the steps to USB Boot into any installed Operating System or Tool that you’ve previously added to your drive.

  1. Accessing BIOS or UEFI Settings – Restart your computer and proceed to access your BIOS or UEFI. This is usually done by pressing F2, F12, Delete, or the Esc key. Refer to your computer or motherboard manual to find the correct key for your system.
  2. Change Boot Order – In the BIOS/UEFI settings, navigate to the “Boot” or “Boot Order” section. Change the boot order so that the USB drive is the first boot option. This allows the computer to check the USB drive for bootable media before trying the internal storage.
  3. Save Changes and Exit – Save the changes you made to the boot order and exit the BIOS/UEFI settings. This will restart your computer.
  4. Finally, Select an OS to Boot – Your computer should now be booting from the USB drive into a Boot Menu. Simply select the Operating System or Tool you wish to boot from and then press enter. Now follow any additional prompts to make selections for custom booting.

That’s really all there is to it. If all went well, then you should be booting your favorite distributions from your custom MultiBoot USB drive!

Creating a MultiBoot Bootable USB Flash Drive (Linux)

The following instructions were performed from a running Ubuntu host. These steps assume that you have gzip and WINE packages installed on your system. If not, you’ll need to install them both before continuing.

  1. Open a terminal. Ctrl+Alt+T
  2. Next, cd to your desktop:
    cd Desktop
  3. Download YUMI4Linux gzipped tarball using wget:
    wget https://yumiusb.com/downloads/YUMI/YUMI4Linux.tar.gz
  4. Extract the archive:
    (Note: you may be able to just double click the file to extract.)
tar xzvf YUMI4Linux.tar.gz
  • Switch to the extracted folder:
    cd YUMI4Linux
  • Set permissions + run the YUMI Linux shell script:
    chmod +x ./YUMI.sh && ./YUMI.sh

When the script finishes, it will launch the included YUMI-exFAT-#.exe executable file from WINE, enabling you to add bootable ISOs and create persistence files. Note that this tool will only display drives that have already been prepared with YUMI exFAT.

Distributions and tools can be added or removed at any time on prepared drives with this stand alone .exe.
To run the tool at a later time, simply execute the file using WINE as follows:

wine YUMI-exFAT*

Note: You can also copy the YUMI-exFAT-#.exe to another location and run it elsewhere, if you’d like.

How a YUMI Multisystem Bootable USB Works

YUMI (Your Universal Multiboot Installer) enables each user to create their own custom Multiboot UFD containing only the distributions they want. Presented in the order by which they are installed. A new distribution can also be added to the bootable device each time the tool is run.

If you run the tool from the same location you store ISO files, then they should be auto detected, eliminating the need to browse for each ISO.
Other Notes: If MultibootISOs or the Legacy variant was previously used, you must reformat the drive, and start over. The exFAT variant is not compatible with the older Multiboot ISO tools.

Troubleshooting, Known Issues, Bugs

As per the official documentation, Debian requires the persistent block file and label to be named persistence (which was previously live-rw), and it must hold a persistence.conf file containing / Union.* This has been fixed and currently works for some Debian based distributions such as KALI Linux with persistence. However, the persistence feature still remains broken with the latest official Debian distribution. I’m wondering if Debian will only detect persistent partitions and no longer supports persistent block files?

Excluding a Drive from being detected: To exclude a drive from being detected by YUMI, simply create a blank file called excludedrive.txt and place it at the root of the drive you want to be excluded.

ACPI=OFF ~ disable ACPI (Advanced Configuration and Power Interface): When booting Linux distributions from some laptops such as the Lenovo Yoga with a touchscreen, the acpi=off boot parameter might be necessary in order to successfully boot up.

My PC wont Boot from flash drive, but BIOS supports USB boot: Some flash drives ship formatted without a partition, but the boot methods we’re using require a USB drive to contain a partition with a MBR (Master Boot Record). To ensure compatibility, you’ll need to allow the installer to prepare your device. Make sure you’ve backed up any data you wish to keep before preparing the drive.

TAILS not booting: TAILS – If your Multiboot Bootable USB is detected as a “fixed” hard drive and not a “removable” disk, (a few of the larger AXE and SanDisk drives have the removable bit flipped this way), in which case you need to remove any occurrence of the boot parameter “live-media=removable”.

No Floppy Drive: If you don’t have a floppy drive and get fd0 errors while booting, simply add floppy.allowed_drive_mask=0 to the append line for the troubled entry. Although the best fix is to simply disable floppy in BIOS.

Persistently Saving Changes: A casper-rw persistence feature can be used for most Ubuntu based distributions. Yes, you can also have multiple persistent distributions, as each distro utilizes its own casper-rw or live-rw block file.

Adding Ophcrack Tables: In order to load Ophcrack tables, the tables folder might need to exist at the root directory of the USB device; (example F:\tables\vista_free). You can get Ophcrack Tables from the Official Ophcrack site. Once downloaded, simply unzip them to the root of your USB. Because you’re using this method, you can have your Windows 11, 10, 7, XP tables all working together on the same device.
