NTBOOT7z: Simplify Your Multiboot USB Setup If you have ever built a custom multiboot USB drive using grub4dos, you may have encountered NTBOOT (often found as NTBOOT.7z). Created by developer chenall, this powerful script is a staple in the multiboot community for its ability to boot Windows-based environments—like WinPE, VHDs, and WIM files—directly from a custom boot menu.

NTBOOT7Z bypasses this by allowing the Windows Boot Manager to mount a Virtual Hard Disk (VHD) or a Windows Imaging Format (WIM) file as if it were a physical drive. This is the foundation of "Native VHD Booting." 2. Ramdisk Loading ntboot7z
