Yes, but for various reasons it would be more nice, if I just could
patch ntldr, leaving the rest up to GRUB. --- Using GRUB makes it
possible to have more than 30 Windows Versions on one machine, since
we are only testing German, English and Chinese at the moment.
Assume French, Japanese, Korean, Hindi, Spain, ...

It would be nice enough if one could tell us exactly how MBR,
partition boot sector and ntldr interact and work, then what is
required to make ntldr find "boot.ini".

AFAIK does the MBR load the first active primary partition boot
block (an other 512 Bytes). This loads parts of ntldr. Then jumps to
a place within ntldr (ntldr is not started at position 0x0 in the
file). Where exactly GRUB would have to jump in into ntldr I do not
know, as I do not know where this information is placed in ntldr.

Any helpful documentation I'd appreciate!
