Ntloader is a bootloader for NT6+ WIM, VHD and VHDX images.
Ntloader supports BIOS (i386) and UEFI (i386, x86_64, arm64) environments.
It is recommended to use GRUB2 (>=2.12) or GRUB4DOS to boot NTloader.
The source code is maintained in a git repository at https://github.com/grub4dos/ntloader.
You can download the latest version of the binary from GitHub Releases.
Extract ntloader and initrd.cpio onto the disk, and modify the bootloader menu to boot Windows from a FAT/NTFS/exFAT partition.
