I just wanted to add some info for anyone trying to do this in the future:
I have a mid 2012 cMP 5,2 ... I have upgraded the processors to dual Xenon 5690 (3.5GHz) CPUs, 48GB Ram, Nvidia GTX 1080Ti and I just had a hell of a time getting windows 10 onto boot camp onto it.
Here's what worked (for me)...
A real Windows 10 install DVD (i used windows 10 home) -- no way a USB key would boot, plist hacks included. No way. Had to go DVD (others here seem to have success downloading ISO from microsoft and extracting to a DVD to boot into... not sure what format you'd burn the DVD as, perhaps just universal format... i'm not sure though, i had a real windows disk).
A separate hard drive not a partitioned one. I formatted it first in disk utility as Windows NT.
At first many install attempts failed ... until i removed all the drives EXCEPT that one blank NT drive, and then the windows dvd was able to install to it.
I just finished doing it again (this time onto a SSD) and realized THIS TIME i had 2 drives installed. my mac hd and my bland win HD. But I also realized that this was appeared on the device 0 bus! so that is ACTUALLY the key, (i was mystified by some users saying you don't have to remove drives and some saying you do, now having failed with other drives in, then removing them, then getting my win drive to install (it was the only one so of course it was device 0), then putting a mac drive back in, turns out with both drives in, the windows one is still dev 0 so it now works as an install target even alongside other disks. That's the key. Foolproof method: take your other drives out. Or if you can ensure your windows drive is device 0, then you won't have to.
after windows installed, just open your bootcamp folder you downloaded (onto a usb thumb drive or whatever) version 5.1.5621 as others have said, and run setup.exe ... for me it worked without fail. all installers ran automatically from that one script. Others have noted that if it fails you have to run each installer in each driver folder individually. I didn't. I just ran setup.exe and i'm up and running.
Good luck
Tom.
BootCamp cannot see APFS formatted drives. If your drives are APFS then they will not be available to BootCamp.Any input on that "strange behavior" ?? All drives except the one it is installed on are not appearing anywhere ! And there are no red marks or warning signs on the device manager, everything seems to have been installed right !
Hello TOMBOT2000 !
i'm having a strange reaction from a newly installed windows 7 here on my mac pro 4 (flashed to 5).
I couldn't install windows 7 (neither bootcamp nor manual install would work) when the mac rebooted from the windows 7 DVD (which i know for SURE works) it would eventually get stuck at a blinking cursor in the upper left corner on a black background (DOS style if you know what i mean).
I've read here (from this post actually and another one) that the only way to get this working was to unplug all HFS/APFS drives and put the SSD (ntfs formatted) in bay 1... i did it, and to my surprise, it worked like a charm (the "why" remains a mystery but hey... i wont sweat it.)
But know that i've plugged back everyhting (SSD in HFS and HDDs in NTFS and HFS too), when i boot to my windows 7 (with bootcamp driver package installed of course!) it cannot "see" ANY DRIVE except the one it is installed on !!! I've got another NTFS drive which is not seen either and the superdrive, the optical drive from which i've installed windows 7 in the first place (!) is not seen either !!
As a "plus" the eject button from the keyboard does not work for superdrive (quite logical if it's not detected one might say..)
i'll try a SMC reset and PRAM reset too... Any input on that "strange behavior" ?? All drives except the one it is installed on are not appearing anywhere ! And there are no red marks or warning signs on the device manager, everything seems to have been installed right !
Yes indeed, i have an NTFS drive and an HFS drive too (and the optical drive of course). Besides, i've got an APFS drive for HS but i have installed the free APFS driver (beta version) from paragon anyway (which works really well by the way).. so this is not the issue here trust me.BootCamp cannot see APFS formatted drives. If your drives are APFS then they will not be available to BootCamp.
Hm i'm not sure i understand the question precisely.. So i'll try to answer the question in every aspect it may suggest..Which bootdrives did you use?
/Per
I did the windows installation "manually" since bootcamp app was a pain in the a**.
you mean bootcamp driver package 5.1.5621 ? yes i've already installed it of course. All went well from that point of vue.. every controller on every bus and every port has it's driver installed..disk is bootable and everything works really ! but it still cannot see the other drives and dvd player/writer...Yes, you have done everything right. But, do Windows come the apple drives? For the keyboard? Does Windows know that it has been installed on a Mac? No it have not. You need the drives to get the hardware to function right.
Use BootCamp 5 and BootCamp 4

…the computer will reboot but I get an error that says "No bootable device --insert boot disk and press any key"
It says here that MacPro5,1 does not support booting Windows into EFI mode: https://support.twocanoes.com/hc/en-us/articles/115003286483
I am quite sure that's only base on Windows installation by using Bootcamp.
Yes, sure seems like it since it absolutely works to boot into EFI mode if omitting Bootcamp.
By the way, do you know of a way to get built-in audio to work when booted into Windows 10 in EFI mode? If not I was thinking I perhaps can install the driver for my USB audio card and use only that for audio.
Did you download the BootCamp driver package and install it after you installed Windows (just as you would do with any standard purchased motherboard)? That should have all the device drivers you need for the Mac under Windows.
I have just installed the release version of Paragon's APFS for Windows. I was hoping I might be able to boot back into MacOS if this software was able to write an APFS boot efi partition, but no luck. In Win10 I still have to click on Restart in Mac OSX from the Bootcamp icon, which boots into Recovery HD, and from there select my primary MacOS drive.
Interesting, that will automatically reboot you to Recovery Partition?
Thanks SnakeCoils for that stiff explanation!
But unfortunately there some more bugs out there...
Maybe i am blind - correct me please, but i can not find any similar cases.
I followed your tutorial but if i reattach my PCIe SSD the Win10 (1903) wont come up anymore.
A blinking underscore on black screen - nothing more. (same as i tried to boot from Win10 DVD)
Setup: cMP5,1 / 10.13.6@PCIe SSD (IO Crest) / Win10@SSD (Slot3) / GT120 (Bootscreen) / Vega 56 / 40GB RAM
StepByStep: Bootcamp Assistant > select SSD (format) > shutdown - Unplug all but SSD in Slot3 - insert Win10-DVD - Bootup with "C" - Diskpart > Clean - Install Win > doing all updates to 1903 - Brigadier > Bootcamp5 (install BT and Audio) > Bootcamp6 (install bootcamp.msi) - Reboot (all is fine till now) - shutdown > reattach PCIeSSD - reboot (macOS see partition Bootcamp but not shown in Startvolume pane) - reboot holding "alt" tried "Windows" = black screen + promt
What i doing wrong?!
Thanks in advance
