Hello MR.

As I want to play a games (MGSV) on my 2013 quad Mac Pro (D300 + macOS 10.12), I need to install windows 10 in my nmp.
But as I tried even method I failed.

1.) By Boot camp assistant, everything go smoothly but at the end windows installer show "windows cannot modify boot configure".
2) I just try to divide my SSD to 2 partition by disk utility, use Rufus to create windows 10 usb media. An installer failed at disk selection it tell "windows cannot install on MBR volume <- (but my Mac surely GPT)".

How i can install windows on nmp. please help me.

Do you mind telling me what a "nmp" is? I am not familiar with that term.
 
nmp new mac pro
cmp clasic mac pro
can you just use boot camp assistant to install windows instead of doing it manually, worth a try
 
he mentions using disc utility to partition his HD instead of using bootcamp assistant to partition the HD which might be the problem that tha partition is not correctly done.
 
Thanks for all reply.

I have done 2 separately ways.

First, I've install macOS Sierra -> launch boot camp assistant -> create windows installer partition -> start windows installation -> and end up at "windows cannot modify boot configure".

Second, I've boot to macOS recovery partition -> delete all partition -> create single Macintosh HD -> reinstall clean macOS Sierra -> Divide my SSD to 2 partition by diskutility -> use Rufus to create windows 10 usb media -> start windows installation -> An installer failed at disk selection it tell "windows cannot install on MBR volume <- (but my Mac surely GPT)".

Now I cannot install windows 10 in my Mac T_T.

It sounds like you will need to delete the Hybrid MBR that Windows is seeing.

Can I just use windows installer dvd and remove all available partition?

Boot OS X from an external USB drive

In terminal: diskutil list

Now you see all all disks and all partitions. Check the dev/disk number you want to erase.

Erase volumes, example: diskutil eraseVolume HFS+ Blank /dev/disk0s1

I devised a method immediately around the launch of Windows 10 to get around all boot camp issues.

My method was originally meant to get Windows 10 on unsupported machines. But in reality, it should work on any Intel Mac. Even newer ones such as yours.

Take a look at the tutorial I wrote here:

Do you want to clear the entire drive and erase all of the data? If so, you could do that. I would recommend booting into Internet Recovery (Cmd+Option+R) and erase the disk in Disk Utility from there. Do you intend on installing OS X and Windows 10, or only Windows 10?

If you are comfortable in Terminal, use gdisk to remove the hybrid partition:

https://sourceforge.net/projects/gptfdisk/
 
Now all I have is this.

Code: 
/dev/disk0 (internal, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *251.0 GB   disk0
   1:                        EFI EFI                     209.7 MB   disk0s1
   2:                  Apple_HFS Macintosh HD            250.1 GB   disk0s2
   3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3

How can I check if I have hybrid MBR partition?
 
If you run sudo gdisk /dev/disk0 it should tell you.

Yep, to monkeybagel, you'll see a lot of this:

nMP= New Mac Pro or Nano Mac Pro
cMP - Classic Mac Pro or Cheese Grater Mac Pro

Welcome to the Mac Pro forum.

Where do these acronyms come from? It seems they only appear on this site's forums.

Thanks for reply is this means hybrid MBR?

Code: 
Partition table scan:
  MBR: protective
  BSD: not present
  APM: not present
  GPT: present

Found valid GPT with protective MBR; using GPT.

I've had the same issue with boot camp on a couple of different macs, a nMP and a rMBP. The issue was boot camp wasn't creating the windows partition correctly. When you are in the windows setup wizard, there's a part where you can modify the windows partitions - just reformat the partition boot camp has set aside for Windows.
