I am attempting to install Windows 10 x64 (64-bit) on a device that only has 32-bit UEFI (for the moment)
Since x64 Linux can be booted via a custom 32-bit GRUB.. I assume it could also do the same for windows, but "how to use grub to bypass a 32bit uefi to boot windows 10 x64" seems to indicate otherwise, though the explanation given does not completely explain why (to me at least).
I believe GRUB's 32-bit EFI SHOULD be able to load Window's 64-bit EFI.
Alternatively, is it possible to use grub's newish 'ntldr-mod' to run windows x64 install bootmgr? (howto start WINDOWS OS installation on hard disk with grub2)
This question will likely evolve based on the answers.

'Architectures must match' is not a valid answer.
