EFI Windows has some advantages, you may google that, but for general usage, a user shouldn't feel any difference.
Post #1 Appendix has the procedure to install EFI Windows via OpenCore safely
OpenCore on the Mac Pro
This guide explains how to use the excellent OpenCore boot loader to install, run, and update the latest version of macOS on the MacPro5,1, resulting in a clean, unaltered operating system just like on a supported Mac.

OpenCore only support EFI Windows
OKAY!
This is a big difference.
Maybe it should be noted even in the #1 post (about OpenCore)?
Since we can convert existing legacy Windows into EFI Windows, therefore, that isn't really a huge matter in general.
How to: Boot Camp without a Boot Screen
Yes Intro : For install Win10 on cMP you need DVD bootable with Win10 and press "c" on cMP boot to start on DVD, and install Win10. Now I suppose as me you can boot on Win10 from your cMP, if not please remove all your other boot drive (Mac OS, ...) to be sure to boot only first on Win10. 1)...

Well, it is for me, I'm trying to install win10 (yet still failing).Since we can convert existing legacy Windows into EFI Windows, therefore, that isn't really a huge matter in general.

Nine "guides" out of ten says "use legacy install" (1/10 says how to use it).
I'm planning to use gtx760 with mp5,1 & win10.
Should I install OpenCore first and then EFI windows?
Or should I install in legacy mode, then convert to EFI (need another windows machine for this?) and then install OpenCore?
How do I keep the mp's fw safe from windows install messing it up?
I'm digging and chcecking old hdd's from boxes and drawers to test this out and so far found 3 hdd's, where win10 installation says, that there's a problem with the drive.
How does the messed up fw show up? Does it corrupt hard drives?

How do I uninstall or install "control panel" with Brigadier?
So, this guide is outdated and will not work.
Step 23: "Boot Camp requires that your computer is running Windows 7".
But Step 29 still works, so the iMacPro's bootcamp apps are installed...and...
It works!
I'm running win10 build 18363 in legacy mode (=from MBR disk).
Next 5770 out and gtx760 in...
Aaand 760 works with no hickups.
Anybody knows does win10 work with 5770 + 760 both installed?
(Had those in mp3,1 for years, but never installed windows on that mac...)

Hello, hope you can help.
I have a Mac pro 5,1 2012 with opencore, Mojave and Big Sur on separate drives.
I installed Windows 10 on a separate hard drive. All went well following this guide: https://crystalidea.com/blog/classic-mac-pro-and-windows
When I am in Mac OSMojave, I can select the bootcamp partition in the start-up disc but when the Mac boots I don't see the windows partition in the opencore bootpicker.
The mac boots back into Mojave.
Any idea what I need to do to get windows to show on opencore bootpicker and switch back and forward between the mac and windows.
Thanks

Let it start 3 times, if all fail in a roll, should go to recovery mode automatically. Then select safe mode at there usually can fix the issue.
What's you've done to the Windows drive should not affect your mac or macOS drive.
As long as you boot via OpenCore, no cert will be written into the BootROM.
OpenCore doesn't support legacy OS.
Disable that unknown "ghost" device is better than remove it (then auto scan will bring it back).
Mac Pro 5,1
SAPPHIRE PULSE Radeon RX 580 8GB
One SSD installed Mojave, another SSD installed Windows 10 2004, MBR
Installed BootCAMP through brigadier and everything works perfectly except I couldn't switch back from Windows to Mac. I've done another MacPro5,1 for the client and worked without problem.
Tried different pkg for iMacPro1,1 also the latest 061-97204
Wiped SSD and re-installed Mojave a couple of times with different DIsk format, it stayed as APFS
From Windows side bootcamp I could changed to Mojave or other installation USB, but not to the SSD.
Eventually, for testing I moved the Mojave to Bay 1 and it worked. I didn't read through the whole thread if someone said this before then ignore my post.
Just want to add my experience and it might help someone without pulling their hair off.

Same here. "Boot Camp requires that your computer is running Windows 7". How can I fix this?
Not sure if this is the right place to ask but here goes;
Currently have opencore working, win 10 installed on a SATA SSD in bay 2. I am considering using a NVME as my boot drive for Win 10 (I only had a 128GB SSD when I initially did the install, something I regret as I am running out of space).
Would it be safe to clone the current install of win 10 onto the NVME then install it onto one of my PCIEs?
Thanks.

I haven't do that for a long time already, not sure if still the same for the latest Windows 10.
But the work around was by executing the bootcamp.msi as admin in DOS prompt
How to: Boot Camp without a Boot Screen
I don't remember uninstalling any bootcamp drivers before 6. But I had to uninstall before 6.1

Anyone noticed Bootcamp update solving this issue?
Today i was reinstalling Windows after a long time, and as i was downloading Brigadier i've checked Apple Software Updates, just for laugh. There was a Bootcamp update "solving the issue of booting back into macos".
So i installed it, manually since there is a good old certificate error, and i got my Mojave APFS SSD back in booting options.

Excellent guide (posting #214)! 
👍👍👍
I've successfully installed Windows 7 using your method, followed by installing the Windows driver for my Sapphire Vapor-X HD-7950 GPU card (after rebooting the Windows desktop now fills my entire screen, unlike a small square in the middle before installing the driver).
I might add that before going ahead with the Windows installation from the DVD, I formatted (erased) the drive I was going ot use for this as "ExFAT" (within MacOS, and using Disk Utility) and most importantly: gave the disk a name so it would be easily recognized in the Windows installation process "Where do you want to install Windows?" (step 4) so as not so easily accidently erase/format the wrong drive.
Once I selected the correct drive I proceeded as instructed here. As far as I remember though, in step 5, I only found a single drive partition (not 4 as in the example here), but I suppose that's just because I already pre-formatted it without doing anything else.
I also (physically) removed all other drives from my cMP except the MacOS 10.13.6 startup SSD and of course the hard drive I would use for Windows. That way I would completely eliminate messing up my Mac drives.
I've followed the guide to the letter and most of it has worked out fine, but have gotten into some problems when installing the Bootcamp software (step 9 and onwards). Perhaps someone can help me out?
Not sure how small a USB flash drive is sufficient, but I used a 32 GB one.
Worked fine. Note: once you've pressed the RETURN key nothing appears to happen!
Hang in there! Just wait for a while (it probably took around 1-2 minutes here) and things will start happening on the screen followed by the progress in percent, then a whole lot of other things.
So just be patient and wait until it's done (the command prompt comes back).
Note 2: the above process apparently downloads and installs a Bootcamp-xxx-xxxxx folder on the USB flash drive in case you've been looking to find it. Fortunately my Bootcamp folder wasn't empty.
Similar procedure to above, so be patient even though nothing seems to happen.
The command will create another Bootcamp folder on the USB flash drive and you'll see the Windows command prompt again in the CMD window when done.
First quit the existing CMD window (click the "X" on the top-right hand corner).
Next, go to the Windows "Start" button like you did last time, type CMD in its search field, and when it pops up as (the one and only result), right-click on it and select "Run as administrator".
This doesn't work (and gives me an error message: "The system cannot find the path specified") as there's no "Bootcamp" sub-folder of "Bootcamp5" to be found.
If I double-click "Bootcamp5" to open it, this is what it contains:
So, I assume the above path must be an error and instead I enter the following (which works):
A Bootcamp installer window pops up:
So far so good.....
I'll post this, continue the installation, reboot and continue with the process (I'm doing all of this within Windows).
By the way: I was struggling to find a way to make screenshots in Windows (I'm using an Apple extended wired keyboard and can't figure out which keys to use), but then I discovered an app named "Snipping tool" which you'll find by going to the Windows "Start" menu, click on "All programs" at the bottom (in case you don't already see this app), go to the "Accessories" folder, and there you'll find it.
OK, on with the Bootcamp installation part, reboot and I'll get back here again.

(within Windows), right-click on the USB flash drive (E: here as well, just like in the guide), then select "Format" from the pop-up menu. I just went with the default values, making it an ExFAT drive (which I think may be readable within MacOS as well).
Click on the "Start" button (Windows logo, bottom left of the screen), then type CMD in the search-field, which then opens the "CMD" terminal tool window (similar to the MacOS Terminal app).

Everything looked good for a while, until the "Keyagent" part came up and after a little while was followed by an error message:
So I pressed "Retry", but got the same error message again.
I then pressed "Ignore" which then allowed me to continue with the installation process.... for a while:
Same thing here. Pressed "Retry", same error message again, then pressed "Ignore" to continue, so I choose to "Ignore".
Following this I'm immediately shown a "Bootcamp installer completed":
I assume the computer will reboot after having pressed the "Finish" button, so I'm going to post this, press that button and see what happens next....
