    Hello everyone,

    Really hoping someone can help. I am giving my Mac Pro 4,1 (Flashed to 5,1) to a friend, i have wiped all my drives and have put one drive back in the Mac Pro.

    I am trying to install Windows 10 by DVD (like I did originally) but soon after Windows 10 is installed, when I install bootcamp drivers 5.1.5621 (as i did originally) the system blue screens a few seconds after logging in. I don't have OSX installed and never have on this machine, it was a Windows 10 only machine.

    I have no idea what to do.. it used to work for me..I had upgraded to an RX580. I am currently using the old Saphire EFI card to reinstall Windows and the Bootcamp drivers. I will then try and uninstall all the graphics drivers installed through the bootcamp ones and then swap the card with the RX580 and manually install it's drivers.

    Anyone have any idea what I could be doing wrong?

    Is it also really necessary to install the bootcamp drivers? As Windows seems to find most things anyway.

    If you install Windows in EFI mode, and boot from the Sapphire HD7950 Mac Edition card's Mac EFI ROM, that can cause BSOD.

    If there is only one hard drive in the cMP which is Windows. There is no need to use EFI GPU, you can simply shutdown, swap the RX580 back in, boot the cMP and see if that make any difference.

    Thanks for the reply!

    I am installing Windows 10 by the DVD. I did this originally and used the 5.1.5621 bootcamp driver .exe and everything worked fine.

    Now that i formatted the drive to do a fresh install for my friend, using the same method no longer works. (I did have the RX580 in when i first tried today and it BSOD, which is why i went back to the old Saphire in case that was an issue)

    Turns out it's not, no matter what i do, after I install 5.1.5621 and restart, I get a BSOD seconds after logging in. If I don't install the drivers everything is fine.

    Is there any negatives to not installing them? (He won't be using any apple keyboard or mouse, just normal ones)
