Many users prefer this specific iteration because of its legacy compatibility. Newer versions of WinSetupFromUSB have added support for more modern UEFI features, but in doing so, they sometimes break the "easy" boot process for older Windows XP or specialized DOS-based industrial software.

Abstract

WinSetupFromUSB is a popular but under-documented tool for creating multi-boot USB drives, especially for Windows XP, 7, and Linux installers. Version 0.2.3 (circa 2010–2013) contains a unique hybrid bootloader architecture that enables booting unmodified Windows setup ISOs from USB without floppy emulation — something even Microsoft’s own tools struggled with. This paper reverse engineers its internal bootloaders (grub4dos, syslinux, and a custom MBR) and documents how it achieves boot-time ISO remapping, fake disk signatures, and chainloading across legacy BIOS and early UEFI. We also analyze the “USB readiness check” hack that prevents Windows setup from failing due to disk reordering.
