MultiOS-USB

MultiOS-USB is a versatile, open-source utility designed to create multiboot USB drives capable of hosting multiple operating systems on a single portable device. The project simplifies the process of building a bootable USB by automating the configuration of various boot loaders and file systems, enabling users to install and run diverse operating systems, including Windows, Linux distributions, and diagnostic tools, directly from one drive.

It supports ISO booting and persistence, which allows changes made during live sessions to be retained, making it ideal for testing, troubleshooting, or system recovery.

Features:

BIOS and UEFI support
Secure Boot support (boot, manage uefi keys)
Load UEFI drivers
Launch .efi executables and other boot loaders
Boot Linux from .iso images
Boot WinPE from bootable .wim images
Boot Windows 10/11 installer from ISO (currently, SB must be disabled during installation)
Boot Linux installer from network (experimental)
Boot locally installed systems: Linux, Windows
Automatically update configuration files
Without background services
exFAT file system support
Automatic detection of compatible ISO images (GRUB loopback)
Support for systems without loopback support
Allows customisation of ISO boot menu (for example: custom kernel options)
Support for USB, SSD, nvme, mmcblk, loop, nbd and virtual disks
Support for x86, x86_64
