This BOOTMGR bootcode is proprietary, and it depends on the
targeted Windows version, hence mkntfs cannot insert it.
However mkntfs creates the boot sector of the partition, which
is part of the ntfs file system structure.
Nevertheless can you explain in what circumstances this would
be useful. On several occasions, I have formatted an ntfs
partition before installing Window 7 or Windows 10, and these
installers insert the boot code they want without formatting
the partition. I do not have XP or Vista any more, but I
would be very surprised if they do not insert their own boot
code as well (possibly while reformatting the partition).

No, this is not done while formatting. The Windows formatting
is limited, and the full formatting occurs when the partition
is mounted the first time. So, when upgrading Windows, you can
format with the old version before installing the new one.

mkntfs, then transferring device to Win machine and using command line=20

& Start?!?
Can you explain what you want to boot into ?
