How to multiboot USB with Windows 11, Windows 10 and Linux

If you want to learn how to multiboot USB and create a single USB drive capable of installing Windows 10, Windows 11, and a Linux distribution, the Linux dd + Hybrid ISO Fusion Method is a powerful technique. This method leverages the hybrid nature of many ISO images, which are designed to be directly written to USB drives and remain bootable across different systems.

How to Multiboot USB: The Hybrid ISO Fusion Method with dd

Overview

The core idea is to use the Linux dd command to directly copy ISO images onto a USB drive, exploiting the fact that many modern ISO files are "hybrid"—meaning they contain bootable partitions that can be written directly to a USB device. By carefully combining the ISOs for Windows and Linux, you can create a single multiboot USB that, when booted, allows you to choose which installer to run.

Additional Tips

Hybrid ISO Compatibility: Not all ISOs work perfectly with this method; testing is essential.

Partitioning: You can partition the USB drive beforehand, but many hybrid ISOs are designed to be written directly to the entire device.

Multi-ISO Boot Managers: For more control, combining this method with a boot manager like GRUB can help create a menu to select between images.
