Then run sudo update-grub . Ironically, NTBoot7z is not designed to be launched from Windows Boot Manager directly. You need a third-party bootloader (GRUB, rEFInd, or Syslinux) as the host. However, you can add an entry for GRUB2 to the Windows BCD using bcdedit , then GRUB loads NTBoot7z. Advanced Techniques and Troubleshooting Booting a WIM File (e.g., Windows PE) WIM files are even more space-efficient than ISOs. To boot a Windows PE WIM:

However, if you just want a simple “plug-and-play” USB drive, Ventoy is simpler. And if you only boot Linux ISOs, GRUB’s built-in loopback is sufficient. ntboot7z

Introduction: What is NTBoot7z? In the world of system administration, IT support, and PC repair, booting from installation media is a daily task. Traditionally, this meant burning DVDs, creating bootable USB drives with tools like Rufus, or maintaining complex multi-boot partitions. However, a powerful, lightweight, and often overlooked tool has changed the game: NTBoot7z . Then run sudo update-grub

If you already manage a GRUB-based multiboot environment, adding NTBoot7z is a no-brainer. It gives you the superpower of booting any Windows ISO or WIM on demand, with almost zero setup overhead. However, you can add an entry for GRUB2

is a specialized utility designed to boot Windows operating systems directly from compressed disk image files—specifically ISO (disc image) and WIM (Windows Imaging Format) files—without needing to extract them to a USB drive or hard disk partition. It is an evolution of the legacy ntboot tool, enhanced with native support for 7-Zip’s progressive extraction technology.
