This bootable USB Software can be used to store multiple bootable ISO or Image files on one USB flash drive or (UFD). Then, during computer startup (assuming you have set your computer to boot from the flash drive), you can navigate from an organized folder structure and choose which one to boot from. Bootable distributions and tools can also be uninstalled or removed with the frontend of this tool.

What is a bootable USB?

A bootable USB is a removable storage device (typically a flash drive or micro SD card) that has been configured to USB boot from the software or operating systems stored on it, instead of an internal hard drive. Such a drive might contain system utilities used for diagnostic troubleshooting, malware and antivirus scanning, OS startup repair, etc. Or operating systems such as Linux or Windows that can be run entirely from the removable portable storage device or used as an operating system installer.

Bootable USB drives can be used across a wide range of devices, including desktops, laptops, and embedded systems. Creating a bootable USB stick with multiple ISO files allows you to carry an entire toolkit for installation, recovery, and testing — all in your pocket.

Here are some common reasons and use cases for creating USB bootable drives:

USB Operating System Installation: Bootable USB drives are often used to install or reinstall operating systems like Windows, macOS, Linux, or other specialized operating systems. Users can portably boot from a USB drive just as they would a Live CD or DVD, but without using a CD/DVD media. Then one can follow the same usual installation prompts to set up and install an operating system on their computer’s internal drive.
System Recovery and Repair: USB boot from system recovery tools or system diagnostic utilities. Quickly troubleshoot and repair issues with a computer’s operating system or hardware components while running outside of the native operating environment.
Data Recovery from USB: Can include bootable data recovery software used to recover files from a computer that won’t boot normally due to system failures or malware infections.
Live USB Operating Systems: Certain Linux distributions offer “LiveUSB” versions that can boot from a USB drive. This allows you to run an operating system directly from a USB drive without installing it onto a computer’s hard disk. A Linux Live USB is a bootable Linux USB that can be useful for testing or trying Linux or for using a specific Linux environment on a temporary basis.

Multiboot USB drives are especially useful when working with multiple operating systems or recovery tools. Rather than carrying several USB sticks, you can consolidate everything into one universal boot USB that supports Windows installers, Linux distros, antivirus tools, and even custom ISO files.

How to Create a Bootable USB Drive

To create a bootable USB drive consisting of ISO files, you can use specialized software that copies the necessary files from the operating system or utility to the USB drive. This type of tool will also set up the drive’s boot sector so that the computer can recognize it as a bootable device. YUMI is a software utility that can automatically do all of this for you.
Using YUMI as your multiboot USB creator not only simplifies the bootable media creation process, but also allows for flexibility, letting you add, remove, and update ISOs without formatting the entire drive. Whether you’re preparing a bootable USB for Linux, Windows, or other live environments, YUMI streamlines the entire workflow.

Keep in mind that while preparing, formatting, and making a bootable USB drive, any existing data on the drive is wiped clean and overwritten, so you will want to back up any important files you wish to keep, before proceeding. Additionally, you may need to change the boot order found in your computer’s BIOS or UEFI settings to boot from the USB drive instead of its local internal hard drive.

How can I Boot from USB?

Here are the steps to get your computer to boot from USB using this software:

Insert a prepared YUMI USB bootable flash drive into your computer’s USB port and then power on or restart the PC.
During the system post, (as text starts appearing on the screen), Access BIOS or UEFI with a keyboard shortcut using a hotkey such as F2, F8, F9, F11, F12 or the Del key.
From the list of boot devices set your USB drive to be the first boot device.
Click Save or press F10.
Let your system proceed to startup and boot from the USB thumb drive.

If all went well, your computer should proceed to read and execute the software stored on the bootable USB. Booting from the pendrive instead of the operating system installed on the computer’s internal hard drive.

Using a multiboot USB flash drive built with YUMI means you’ll always have a reliable rescue, installation, or testing environment ready — no matter the situation.

YUMI USB Multiboot Software Variants

Over the years there have been three different variants of this popular USB boot drive creator. Here each evolving iteration is shown in order starting from the latest release.

YUMI exFAT

The YUMI exFAT multiboot USB media creation tool is the latest version and the only one actively maintained. It now uses the Ventoy bootloader, supporting both UEFI and BIOS USB booting through a secondary hidden FAT32 partition, while an exFAT partition is used to store the bootable ISO files. This approach allows for maximum compatibility and flexibility, letting you boot from UEFI or legacy BIOS systems using the same USB drive — ideal for creating a universal multi-system booting USB that works across platforms.

YUMI UEFI

Following the Legacy release, the second iteration of YUMI UEFI was developed to accommodate both BIOS and UEFI USB boot modes, as motherboard manufacturers transitioned from BIOS to UEFI firmware. This USB boot drive creator version only supports booting from USB drives formatted with a FAT32 filesystem. While no longer actively developed, this variant remains useful for users requiring a FAT32-only multiboot USB boot solution for compatibility reasons.

YUMI Legacy

YUMI Legacy was the initial version, supporting only BIOS USB booting and working with USB drives formatted in either NTFS or FAT32 filesystems. Originally developed in 2010, it was later made available to the public in March 2011. This version paved the way for today’s modern multiboot USB tools and remains a lightweight, stable option for legacy system users.

Note: Going forward, only the exFAT variant is recommended, as it uses the most up-to-date USB boot methods for both UEFI and BIOS. If there are specific distributions or features from other versions that you’d like to see supported, please feel free to contact me, and I’ll consider adding them.
