As far as I an tell, Boot Camp creates a UEFI install of Windows 10 on the Late 2016 MBP. I think this has been the case for a while with newer Mac systems.
See here:
https://en.wikipedia.org/wiki/Boot_Camp_(software)#Startup_Disk
Look at the last line in the "Startup Disk" section.
Yep, I just verified it, Boot Camp created a UEFI install of Windows 10 on my MacBook Pro. There are two easy ways to check from within Windows.
The easiest method is to run the "msifno32" command line tool. Once run, find the line that says:
BIOS Mode
If it says "UEFI", it is a UEFI install. If it is hybrid MBR/GPT install, you will see "Legacy".
For the second way, open this file:
c:\Windows\Panther\setupact.log
Look for this string:
Callback_BootEnvironmentDetect: Detected boot environment:
If you see the text "UEFI" at the end of the string, it is a UEFI install. If it is hybrid MBR/GPT install, you will see "BIOS".
Based on this, I see no reason to use an unsupported and convoluted method to be able to install and boot Windows 10 since the MBR/GPT hybrid you mentioned is not used.
