Help Installing Windows 10 on Mac Pro 5,1

--- Post Merged, Jul 24, 2017 ---

This is what I did... download a copy of Windows 10 from Microsoft, put it on a zip drive and used bootcamp to install. I used a separate hard drive just for bootcamp/Windows. You can find instructions online. It takes about an hour maybe longer to complete the install. To go back and forth, from Windows to Mac, there is an option on the bottom right corner to reboot into Mac. In Mac you just have to select the start up disk to go into Windows.

 

Not for me, no. I have the mid-2012, 2x 3.46 6 core, running 10.11.6... just haven't gotten around to updating. Good luck!

 

Use a disc is the easiest way to do that it. Bootcamp assistant still able to install Windows 10. The only step require work around is after Windows installation, you need to use command prompt to install bootcamp driver. This is the easiest way to do it, but in lagacy mode AFAIK.

 

Yes, burn the Windows ISO to DVD, don't use a flash drive.
Then, hold down OPTION key when you boot and select the DVD called EFI.
This will setup Windows 10 in UEFI mode offering the best performance.

 

Wasn't there also some issue that your Windows drive should be in bay 1? Or was that for something else?

 

It doesn't matter which bay to install Windows 10, but I had to completely remove all other drives.

 

I my case, I can keep all other drives (both OSX and data) connected, they won't affect the installation.

And the Windows drive can be at any bay (including the optical bay).

 

UEFI install doesn't make a noticable performance difference. The CPUs are too old to let any 'new' components shine.

 

Not true. UEFI mode enables AHCI on drives without having to hack it in by force.
AHCI has a significant impact on performance.

 

Unless your general workflow can utilise QD32, otherwise, the real world difference is not significant.

4K random read / write won't be affect. That's the main reason to use SSD. TRIM won't be affected.

Sequential speed may able to go up about 20%. But if that's really important, using a cMP is already the wrong decision.

For HDD, doesn't really matter IMO.

 

You're missing the obvious one, CPU usage when accessing the disk in ATA mode can be huge, sometimes maxing out an X5690 core.

 

I have tested this and found the difference negligible. I posted results here when Win 10 came out when I was first person to install it on cMP.

Even my workstation PC runs in legacy mode and every component benchmark hits the manufacturer specification.

 

As Apple says cMP doesn't support W10 go with 5.1.5621 - https://support.apple.com/kb/dl1720?locale=en_US

 

5.1.5621

 

Paragon HFS+

Also, if you have Magic Mouse / BT 4.0 card etc. you need to manually extract the AppleBluetoothInstaller64.exe from the 5.1.5640 drivers. Otherwise, the card won't work, or the mouse won't scroll.

For bootcamp driver installation under Windows 10, I think you need to run the bootcamp.msi from command prompt (as admin). From memory, the setup.exe won't work properly.

 

i did the plist bootcamp hack to get it to let me install win10 but then it was smooth after that. this on 4,1->5,1 sierra latest

 

Zip drive or thumb drive I haven't seen a Zip drive in a decade

 

How do you figure out if you already have an install in UEFI mode? Was a while ago now but I'm sure I installed on an old Windows box, updated it fully and installed the bootcamp drivers and then just moved that to my Mac. If I can get better performance I might reinstall.

 

C'mon man. Surely you've used Google before?

Hmmm. Thx.
