YUMI – Multiboot USB Creator
YUMI (Your Universal Multiboot Installer), is the successor to our MultibootISOs. It can be used to create a Multiboot Bootable USB Flash Drive containing multiple operating systems, antivirus utilities, disc cloning, diagnostic tools, and more. Contrary to MultiBootISOs which used grub to boot ISO files directly from USB, YUMI uses syslinux to boot extracted distributions stored on the USB device, and reverts to using grub to Boot Multiple ISO files from USB, if necessary.
Aside from a few distributions, all files are stored within the Multiboot folder, making for a nicely organized Portable Multiboot USB Drive that can still be used for other storage purposes.
YUMI was originally intended to be used to store and run various "LIVE Linux" Operating Systems and tools from USB. Using YUMI to install Linux from USB to a Hard Drive works on some but not all distributions. (I'm working to address this).
YUMI Multiboot Bootable USB Flash Drive Creation
YUMI works much like Universal USB Installer, except it can be used to add more than one distribution to run Live from your Thumb Drive. USB Bootable Distributions can also be uninstalled using the same tool!

The following YUMI UEFI version is a work in progress that utilize GRUB2 for both EFI and BIOS booting. NOTE it is NOT backwards compatible with standard YUMI, and the distributions it currently supports are limited!
YUMI UEFI MD5: E9CF4A65B7629B1D11DD8CEC30010023
Important YUMI UEFI info: You'll need to disable secure boot (if it's enabled). Also note that 32bit UEFI firmware does not work yet.
Running YUMI from LINUX: WINE works well for running YUMI from a Linux OS, with the exception of Fat32 Formatting the USB drive. See How To
IMPORTANT NOTES: Your USB drive must be Fat16/Fat32/NTFS formatted, otherwise Syslinux will fail and your drive will NOT Boot. NTFS may not work with every distribution but is required for storing files over 4GB. YUMI UEFI must use Fat32 format.
YUMI can be used to format your select USB drive, but be aware that all partitions on the selected drive 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 MultiSystem Bootable USB Drive
- Fat32 or *NTFS Formatted USB Flash or USB Hard Drive
- PC that can boot from USB
- Windows Vista/7/8/10 or Linux/Mac OS with (WINE)
- Your selection of ISO Files
Please inform me of unlisted "FREE" Live Linux distributions or version revisions, and I will attempt to update YUMI to support them. Software developers who wish to have their "PAID" software added, can send me a copy to try.

How to Create a MultiBoot USB Flash Drive (Windows)
- Run* YUMI-22.214.171.124.exe following the onscreen instructions
- Run the tool again to Add More ISOs/Distributions to your Drive
- Restart your PC setting it to boot from the USB device
- Select a distribution to Boot from the Menu and enjoy!
That's all there is to it. You should now be booting your favorite distributions from your custom Multi-Boot USB device!
Creating a YUMI MultiBoot USB Flash Drive (Linux)
The following instructions were performed from an Ubuntu 16.04 host environment.
I. Format your USB Flash Drive to use a Single Partition:
- Open a terminal and type
fdisk -l(and note which device is your USB Drive)
fdisk /dev/sdx(replacing x with your actual usb device)
d(to delete the existing partition)
n(to create a new partition)
p(for primary partition)
1(to create the first partition)
Press Enter(to use the first cylinder)
Press Enteragain (to use the default value as the last cylinder)
1(to mark the first partition active "bootable")
t(for partition type)
c(to use fat32 partition)
w(to write the changes and close fdisk)
II. Create a Fat32 Filesystem on the USB Flash Drive:
umount /dev/sdx1(to unmount the mounted partition)
mkfs.vfat -F 32 -n MULTIBOOT /dev/sdx1(to format the partition as fat32)
- Remove and reinsert your USB flash drive, or remount it
III. Install WINE:
- To install WINE from within an Ubuntu operating environment, open a terminal and type sudo apt install wine and press enter. Once WINE is installed, launch YUMI as you normally would by simply clicking the YUMI-126.96.36.199.exe
How YUMI Works: YUMI (Your Universal Multiboot Installer) enables each user to create their own custom Multiboot UFD containing only the distributions they want, in the order by which they are installed. A new distribution can be added to the UFD each time the tool is run.
If you run YUMI from the same location you store ISO files, they should be auto-detected (*See Known Issues Below), eliminating the need to browse for each ISO.
Other Notes: If MultibootISOs was previously used, you must reformat the drive and start over. YUMI uses Syslinux directly, and chainloads to grub only if necessary, so it is not compatible with the older Multiboot ISO tool. Although I do plan to add back most of the capabilities of MultibootISOs as time permits.
Not all Unlisted ISO's can be booted (thus adding Unlisted ISOs is an UNSUPPORTED option).

YUMI Troubleshooting, Known Issues, Bugs:
If you encounter a message stating
An error (1) occurred while executing syslinux. Your USB drive won't be bootable.
The most likely cause is that your USB drive is formatted as exFAT or some other unsupported format. You'll need to reformat as fat32 or NTFS.
If you encounter a message stating
Insane primary (MBR) partition. Can’t find myself on the drive I booted from
First, replace your chain.c32 file located at multiboot/chain.c32 with (you'll need to unzip the file) -> This zipped chain.c32 File
If replacing the chain.c32 file does not fix the problem, your USB drive may be improperly formatted, contains more than one partition or MBR, or your BIOS is not properly detecting the USB drive as USB-HDD, and/or its firmware needs to be updated. You can try these methods to Format and Restore your USB Drive
Windows to Go/Installers
Windows to Go option creates a VHD file that is 20GB in size. As such, it requires the drive to be formatted NTFS. Fat32 cannot support a file more than 4GB in size. Many flash drives you might find at local department stores won't be fast enough. You'll need a Very Fast Flash Drive. When Windows boots from the USB for the first time, it'll go through the setup process and then reboot. You'll need to boot using your Windows to Go menu option a second time to finalize the setup process and finally boot into your full Portable Windows.
-wimboot option stores the extracted Multi Windows Installers in their own directory. -bootmgr option moves the bootmgr and bcd files to root of drive. (note: -bootmgr option does require a Windows Vista or later host to run bcdedit).
Traditional YUMI is not natively UEFI capable. However, it is possible to boot and run your Windows Installers from UEFI. To switch between added Windows versions, navigate to the multiboot/win-directory (replacing win-directory with the Windows version you want to boot) on your USB. Once there, move the bootmgr, bootmgr.efi, and entire boot folder to the root of your USB drive. Then reboot, booting your computer from the UEFI compatible USB. If all went well, it should boot straight into your chosen Windows Installer.
Multiboot folder and volume name.
YUMI tries to store most added distributions within the multiboot folder. This is also the root directory set for syslinux. In some cases, YUMI also expects the Volume Label of your USB drive to be MULTIBOOT in order for OpenSUSE, CentOS and several other distributions to boot. YUMI attempts to automatically create this Volume Label, however it can sometimes fail. Please ensure that the Volume Label of your USB remains MULTIBOOT if you expect your distributions to boot.
When booting linux distributions such as Ubuntu from a Lenovo Yoga with a touchscreen, the acpi=off boot parameter might be necessary in order to successfully boot.
My PC wont Boot from my Flash Drive, but BIOS supports USB boot!
Some Flash Drives ship formatted (without a partition), and YUMI requires the drive to contain a partition or some distributions won't boot. To ensure compatibility, you can use YUMI to format your device as NTFS or Fat32.
How to force a rebuild of the Syslinux MBR:
This is useful if your YUMI prepared USB drive is somehow no longer bootable.
For Newest version of YUMI:
Simply remove libcom32.c32 and the hidden ldlinux.sys file from the multiboot folder on your flash drive, and use YUMI to install any menu item. YUMI will notice that this file is missing and will attempt to repair it.
For Older versions of YUMI:
Delete the hidden ldlinux.sys file from the multiboot folder, and use YUMI to install any menu item. YUMI will notice that this file is missing and will attempt to repair it.
Other Known Issues:
Flacon 4, Hiren's Boot CD, Trinity Rescue Kit, Backtrack, Avira Antivir, and Dr.Web Live CD files are stored outside of the multiboot folder. Most other distribution files remain contained within the multiboot folder. I am open to a simple working solution!
YUMI supports Windows XP Install from USB via ISO. In order for the Windows XP installation to succeed, you must perform the following steps;
1.) To begin an install, select (Stage 1)
2.) Upon first reboot, you must select (Stage 2)
3.) Finally, after (Stage 2) is complete – upon the second reboot, select (Stage 3) to boot the drive where you installed Windows XP. If this option fails, simply remove the USB and reboot!
* YUMI does support NTFS, however not all distributions will boot from an NTFS formatted device. NTFS is required for Windows to Go and distributions containing files over 4GB.
Troubleshooting Boot Errors:
While trying to run an ISO from USB, If you get a Boot error saying:
Error 60: File for drive emulation must be in one contiguous disk area
You'll need to defragment your ISO using one of the following tools:
contig – Command line tool to defragment ISO files.
wincontig – GUI tool to defragment ISO files.
Edit non-booting menu entries for the ISO's you have added via the "Try and Unlisted ISO (GRUB)" options, by editing the corresponding entry in \multiboot\menu\menu.lst
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: YUMI currently enables the casper-rw persistence feature for some (but not all) Ubuntu based distributions. Yes, you can have multiple persistent Ubuntu based distributions, as each distro utilizes its own casper-rw file. * Persistence will NOT work on NTFS formatted USB drives. Some Distributions also will not even boot via NTFS!
Ophcrack Tables: To load Ophcrack tables when booted in this fashion, the tables folder needs to exist at the root directory of the USB device; (example F:\tables\vista_free). Get Ophcrack Tables from the Official Ophcrack site and unzip to your USB. You can have both XP and Vista/7 tables working together.
YUMI on Linux: You can easily run YUMI on a Linux Host via WINE. 🙂
