Anyone have a clean, free guide on how to install Bootcamp on a internal PCIe SSD card that shows as external? The official procedure only works for internally recognized drives.
There's a bottleneck with that guide -- you can't unplug a PCIe card when you need to switch the SSD to the VM.I did it some time ago to run an iMac Pro off a Samsung T3. Basically I think you just use an existing PC or virtual machine to install Windows to the drive, then add in Apple's device drivers once it's booted.
On the Mac Pro 7,1 you'll have to turn off the security boot stuff through recovery mode (command-R while starting up), and use Boot Camp Assistant just to download the drivers to put on a USB key (menubar command). I did both today with no issue, Windows 10 installed very smoothly (on the partitioned Apple SSD).
Edit: here's a guide.
They use a free trial of VMWare as the PC.
I know this is an old post but I have been trying this for too many hours using multiple techniques without success. Based on this post I moved the SSD from PCIE to a USB enclosure and it still didn't work. Windows 10 installs, but won't boot. I get the blue Windows screen then nothing. I have used WintoUSB, and multiple other stepwise processes. Using MacPro 2019. Catalina. New Samsung SSD on a Sonnet Tempo card. I have tried to follow every guide out there carefully.Turns out it’s way easier to just use the official procedure of installing off a bootable USB drive. Clean and runs perfectly.
Which drivers into what folder did you need to move?Just in case someone else reads this thread, I finally solved this. It was a driver issue. I have an XDR monitor running on thunderbolt, which windows did not recognize out of the box. Found an old HDMI monitor and got it done. I had to manually add multiple drivers from the Windows Support folder but so far it seems to be working.
