What is YUMI?
YUMI Multiboot USB creator has been considered by many to be the best tool to create a bootable USB. It replaces our old Multiboot ISOS tool and is also the successor to the Universal USB Installer (UUI). These tools were among the first ever made for the purpose of creating a bootable flash drive.
All bootable ISO files are stored within the YUMI folder. This makes for a nicely organized portable Multiboot USB drive that can still be used for traditional storage purposes.
Though the utility was 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 with most distributions. If you find a distro where the installer does not work, please let me know. You can also use this software to create Bootable Windows Installers, enabling you to easily Install Windows 10 from USB.
YUMI Multiboot Bootable USB Flash Drive Creation
This tool works much like the classical Universal USB Installer or Rufus, except instead of imaging a single ISO to USB, it can be used to store and run more than one distribution from your flash drive. Enabling you to Boot Multiple ISO files from the same device. Distributions can also easily be uninstalled or removed with the tool!
Question: You might be asking, how can I boot from USB with exFAT?
Answer: The YUMI exFAT media creation tool can be used to automatically create an exFAT bootable USB. The following explains key differences between it and all of the older archived, no longer updated YUMI variants:
- YUMI exFAT supports exFAT format & 4GB+ files. BIOS and UEFI USB boot.
- YUMI Legacy (archived) supports NTFS or Fat32 format. BIOS USB boot only.
- YUMI UEFI (archived) Fat32 only. BIOS and UEFI USB booting (distro dependent).
YUMI exFAT (BIOS and UEFI USB Boot)
This is the the latest and suggested variant to use going forward. It 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 drag and drop bootable ISO files into folders onto your flash drive to be automatically detected and added to the boot menu at startup.
YUMI exFAT utilizes a bootloader based on Ventoy2Disk along with a custom YUMI theme and configuration enabling you to use advanced Ventoy boot methods with YUMI's helpful front end. Making it easy to find new distributions to download and try.
Create and manage for example; Arch, Debian, Fedora, and Ubuntu based distributions with persistent images, or make multiple Windows Media Installers. You can even use the software for installing Windows onto USB in which case each distribution is stored and booted from separate VHDx images.
It is also important to note that this variant is backwards compatible with Ventoy. In fact, if you'd like, instead of using YUMI2USB you can copy YUMI-exFAT-126.96.36.199.exe to the same location as your Ventoy2Disk.exe and the multiboot USB boot tool will autodetect and use it instead for performing installation/updates.
How the YUMI App works
YUMI enables each user to create their own custom multiboot UFD containing only the distributions they want. Additional distributions can be added to the bootable USB device each time the tool is run.
After your select drive has been setup by using "Prepare this Device" option, you can proceed use the front end Installer to learn more about and download distributions and tools to put on the selected drive. The front end will automatically create an organized folder structure and then copy each ISO file to the drive for you. This media creation tool will also keep track of your installations, which can come in handy for removal later on.
Your Universal multiboot Installer software can also create persistent storage files for you along with any related .json entries. Note that each Arch, Fedora, Debian or Ubuntu based distribution can have its own persistent storage.
Bootable exFAT Flash Drive Setup and USB Boot Screen
- 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 and persistent block files.
- 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).
Drag and Drop ISO Support:
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 on the USB flash drive. During startup, the system will add entries for discovered items. Stored files can be larger than 4GB.
Is USB Secure Boot Supported?
Yes, this variant makes use of the upstream Ventoy Secure Boot. Simply select VTOYEFI and then set ENROLL_THIS_KEY_IN_MOKMANAGER.cer as the Select Key to be enrolled into the MOK database.
Essentials to create a Multi System Bootable USB Drive

|Boot and Run Windows 11 from VHD on USB||Boot, and run Windows from VHDx on USB. Experiment with running Windows 11 or 10 portably.
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.
Using YUMI on Linux
Question: Can I use YUMI on Linux?
Answer: Yes, you can use the YUMI4Linux "YUMI.sh" script to make a Multiboot bootable USB from within Linux. After preparation, you'll be able to drag and drop ISO files into the YUMI folder on the prepared drive. ISO files stored there will be detected and then added to the menu for USB booting.
Here's how to get started using YUMI in Linux:
The following steps assume that gzip and WINE packages are already installed on your system. If they, aren't you'll want to install them both before proceeding.
- First, open a terminal. Ctrl+Alt+T
- Next, from the open terminal window, cd to your desktop:
- Now download YUMI4Linux gzipped tarball using the wget command:
- Then, use the following tar command to extract the archive:
(Note: you may be able to just double click the file to extract.)
tar xzvf YUMI4Linux.tar.gz
- Use the cd command to switch to the YUMI4Linux folder:
- To set permissions and run the YUMI Linux script from a terminal:
chmod +x ./YUMI.sh && ./YUMI.sh
Once finished, the included YUMI-exFAT-184.108.40.206.exe can be run from WINE to learn more about a distro, download related ISO files, and install additional distributions + create persistence files on any prepared drive.
Note that distros can be conveniently added or removed with the .exe at any time on prepared drives.
To do this, you can simply issue the wine command from the directory containing YUMI-exFAT-220.127.116.11.exe as follows:
FAQ, Known Issues, Bugs
The Persistence feature is currently broken with Newer Debian based distributions due to changes upstream. Debian now requires the persistent block file and label to be named persistence instead of live-rw, and it must hold a persistence.conf file containing / Union. This has been partially Fixed with the recent releases of YUMI exFAT, and works for some distributions such as KALI Linux with persistence.
Cant boot from USB but BIOS/UEFI supports USB booting:
Some flash drives ship formatted (without a partition), but this USB boot tool requires the drive to contain a partition with a MBR (Master Boot Record). To ensure compatibility, the installer will format your device during preparation.
Troubleshooting USB Boot Errors:
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.
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:
The casper-rw persistence feature is used for some (but not all) Debian and Ubuntu based distributions. Yes, you can also have multiple persistent distributions, as each distro utilizes its own block file.
In order to load Ophcrack tables, the tables folder needs 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 the USB. Because you're using this method, you can have your Windows 11/10/8/XP tables all working together on the same device.
Other Known Issues:
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), you'll need to remove occurrences of the boot parameter "live-media=removable" or consequently TAILS will fail to find the live filesystem.
YU MI can be pronounced Yŭh * Mēē or "YUMMY". It is often misspelled YUMMI, YUUMI, or YUMY. Some might also call it Yū * Mēē or "YOU ME".
