Installing Windows 10 on Mac Pro 4,1 (2009) and 5,1 (2010-2012)

 

Make sure you've inserted your USB flash drive or DVD disk with Windows 10 installation. We recommend installing Windows on a drive other than macOS drive to prevent corruption of the data.

 

Please note it must be an internal drive (SATA or NVMe), not external USB drive.

 

Also please note that dual CPU configurations (Mac Pro 4,1/5,1) requires Windows 10 Pro or Enterprise to utilize both CPUs under Windows. Windows 10 Home will only allow to use a single CPU.

 

Step 1

Start your Mac Pro while pressing and holding Option (or ALT key on Windows keyboards) to see boot picker.

 

Click an arrow under EFI boot icon to boot from USB flash drive or DVD install disc.

 

Make sure the USB flash drive is inserted into Mac Pro built-in USB hub (front or rear). Extra USB PCIe cards won't show a bootable flash drive.
