I can explain the general concept and how you might approach how to multiboot USB using a boot manager like Haiku OS Boot Manager, supplemented with standard multiboot techniques.

1. Understanding the Tool

2. Preparing the USB Drive

  • Format your USB drive with a FAT32 or ext4 partition, depending on your target system's boot mode.
  • Copy the ISO images for:
  • Windows 10
  • Windows 11
  • Linux distribution (e.g., Ubuntu)
  • Place these ISO files into dedicated folders on the USB drive for organization.

3. Installing Haiku OS Boot Manager

  • The process involves installing Haiku OS Boot Manager as the primary bootloader on the USB.
  • This can be done by copying the Boot Manager files into the drive and configuring the boot menu.

4. Configuring the Boot Menu

  • You need to manually edit the configuration file for the Boot Manager (similar to menu.lst or grub.cfg) to add entries for each ISO.

5. How to Multiboot USB

  • How to multiboot USB with this setup involves configuring the Boot Manager to recognize each ISO as a boot option.
  • When you boot from the USB, the Boot Manager presents a menu allowing you to select which installer to run.
  • You may need to extract boot files from the Windows and Linux ISOs or use special boot entries that point to ISO images directly, which may require additional tools or manual configuration.
