MP 1,1-5,1 How to install Windows 10 on Mac Pro 5,1 (2009) with Radeon RX580

[Teachermark01]

Dear people,

I have a 2009 5,1 MacPro with Mojave installed on it.
Dual CPU tray 12 cores 3,46hz XEON, 52gb ram 1066mhz, GPU Radeon RX580 8GB.

I want to install Windows 10 near Mojave, but I had some troubles with installing it.
Bootcamp does not work for this machine. I also tried to install it with an other PC and put the Bootcamp Drivers on it and put the SSD in a SATA slot on the mac pro. But then the Efi corrupts and my PCIexpress SSD m.2 won't boot anymore...

With the Radeon I see no bios, so I can't install software from there... whats next?

Kind regards,

Mark

Perhaps you can consider the OpenCore approach; you'll also get a boot screen. The wiki includes a section on installing Windows.

Google the Definitive Mac Pro Upgrade Guide. There's a section on installing Windows via VirtualBox and then installing drivers via Brigadier, THEN you boot natively. That's what I did and it worked like a charm.

I want to game on Windows 10, so the Virtual Box is no option I think? Or is that wrong?

Make a Firmware Dump with Dosdude RomTool. If you boot an uefi Installation you might get certificates what can be problematic.

if Firmware has problems the worst case is getting a non booting Mac Pro. Aka a brick.

VirtualBox is just to get it installed, since RX580s and other cards don’t show boot screens. After it’s all set up with drivers and Bootcamp assistant then you boot natively and install GPU drivers and game on. I play Halo and Star Wars on my Win10 side and it runs it like a champ.

That sounds good, hope I can do this install....

The trickiest part was finding the system disk number via command line. I don’t remember exactly how I did it, but Google helped me out. Hopefully you’re installing on a separate drive and not a partition of your main boot drive—that’ll make it easier.

If you have a spare drive, the easiest (but time-consuming) might be to create a High Sierra install, then use Boot Camp. Boot Camp was supported on the 5,1 until Mojave. This is what I did, worked without a problem. I just pulled the Mojave drive out while doing this to protect it from erasure due to my misreading Disk Utility.

I did this, but at the and he says to boot the mac in Windows. But I have the RX580 and don't get a bootscreen. So can't select the drive. So do I need to change the boot drive in MacOs? And how can I go back to MacOS if I want to?

Kind regards!

You need a bootscreen ... Install MyBootMgr to get one.
