Install Windows on MacPro 5,1 on physical drive through Virtualbox
- SIP disabled. I don't have a native GPU so no boot screen, but I just hold CMD+R 10s after chime sound and wait until I see the recovery screen.
- A drive where windows will be written (avoid partitioning to keep things clean). Mine is plugged into the optical drive bay.
- Bootchamp 1.7. Bootchamp is discontinued but works fine for me. Let me know if you have something better.
- Virtual box
- A Windows 10 iso img. I got a 10 pro edition but the home should be fine too
1 Prepare VM
1-1. Create a new VM for windows (8Gb RAM is enough). Do not add a storage to the vm yet. We will link the drive directly.
1-2. Quit virtualbox
2 Prepare disk
2-1. Erase your disk in disk util (i set mine in exFat but you will reset it during the windows installation)
2-2. Find the disk number. Start a terminal and type
Locate your disk and note its number. Mine was disk0.
During the next steps ALWAYS replace disk0 with your disk. Be extra careful here not to use an incorrect drive as it will be wiped out.
2-3 Change owner and permission. Replace
user with your mac user and disk0 with your disk.
sudo chown user /dev/disk0
2-4 Unmount your disk in diskutil. This is important for concurrency issues between macOS system and virtualbox.
3-1. Create the raw vm disk linked to your physical disk. (replace disk0 with your disk)
VBoxManage internalcommands createrawvmdk -filename "</path/to/file>.vmdk" -rawdisk /dev/disk0
I set my vmdk next to the vm files but feel free to put yours anywhere you want.
3-2 Launch virtualbox. Attach the new created raw disk. Attach also the iso to the optical drive
4 Windows vm installation
4-1 Start the vm and install Windows. When partioning, I prefer to remove all exisiting partitions and create only one
The next steps must be run inside the vm.
4-2 Download brigadier.exe.
4-3 Open a command prompt in admin mode. Cd to brigadier folder and run
brigadier.exe --model MacPro5,1 --install
Let it do its magic (installing bootcamp drivers).
4-4 Shutdown the VM and quit virtualbox
5 Rebooting to windows
5-1 Launch Bootchamp, click on the icon in the menu bar and click on
Restart into windows.
5-2 When you are in Windows, go to update center and make the updates (like the drivers for your GPU).
5-3 You will need to reboot during the update installation. The mac will reboot to macOS, and then you can reboot to windows with bootchamp to finish the updates
