## What it is
MultiOS-USB is a tool that prepares a USB, SSD, or other disk to boot multiple operating systems directly from ISO and WIM images using GRUB2. It supports BIOS and UEFI (including Secure Boot) and automatically detects compatible ISO images.

## Use cases
- create a multiboot usb with several linux isos
- boot windows installer from iso on a usb drive
- make a bootable usb that works with uefi secure boot
- boot winpe from a wim image on usb
- test multiple live linux distros from one usb stick
- manage uefi secure boot keys from a bootable drive

## When to choose
- you want one USB device holding many ISO/WIM images
- you need BIOS and UEFI (with Secure Boot) booting from the same drive
- you want automatic detection and menu generation for compatible ISOs

## When to avoid
- you need to write a single ISO byte-for-byte to a drive (use dd or Rufus)
- you need ARM architecture support (only x86/x86_64)
- you want a graphical Windows-style flashing tool
