How to install Windows 10 and dual boot on your pre-2013 Mac Pro

In the event you’re involved in operating Home windows 10 natively in your ageing pre-2013 Mac Professional whereas nonetheless with the ability to run macOS Mojave, a fast Google search will present that there are various pitfalls and quirks that have to be navigated to make that occur. Issues like boot loaders, System Integrity Protections (SIP), partitioning, GPT, UEFI, legacy bios, eradicating drives, swapping drives, firmware corruption, and far far more are all phrases and points you will want to deal with.

Fortunately, you possibly can keep away from most of those points in case you are prepared to compromise some sophistication in setup and of switching OSs in the event you comply with this information. I can’t be getting too deep into the explanation why some issues work or do not work however there are many discussion board posts and discussions detailing the varied points.

What you will want

A brand new onerous drive

The very first thing we’ll want is a secondary disk drive for the Home windows 10 OS. I purchased a 240GB Kingston SATA SSD for $30.

I purchased a “slower” SATA SSD as a result of it is quicker than a easy HDD, cheap, and utterly suitable with the Mac Professional’s inner SATA specs.

Shopping for a secondary drive permits us to bypass problems with partitioning the macOS drive. On prime of that, utilizing a second drive makes it simpler to get the right home windows 10 partition sort and set up information onto the brand new drive. It will save us from coping with UEFI booting points with macOS Mojave. Extra on that later. All of this assumes that you simply do certainly have a free drive slot in your Mac Professional to put the brand new drive. If not, you will should release a drive slot or comply with one other technique.

A PC that has legacy BIOS booting

The subsequent factor you will want is entry to an older PC or a PC with a motherboard that lets you set the UEFI boot to Legacy BIOS boot. I do know many purists will scoff at this level since a Mac Professional makes use of UEFI for booting however since we will probably be twin booting and macOS Mojave on Mac Execs do not play properly when Home windows 10 is utilizing what’s referred to as a GPT partition for UEFI booting, we’ll utterly bypass the booting issues that include these applied sciences.

We will trick Home windows 10 to make use of the older legacy BIOS booting and to additionally use partitioning referred to as MBR relatively than the newer EUFI and GPT applied sciences. We do that by beginning the Home windows 10 set up on the PC utilizing legacy BIOS defaults after which finishing the set up on the Mac Professional.

A DVD burner

Putting in Home windows 10 from USB supply will implement the UEFI and GPT set up schemes. We need to keep away from that. Putting in from a Home windows 10 DVD will give us the selection of both UEFI with GPT or Legacy BIOS and MBR. We would like the latter.

A burnable DVD

That is for creating our Home windows 10 set up DVD

A USB drive

That is solely required if you do not have a sharable community location to repeat information to your Home windows 10 set up. This must be formatted in order that each macOS and Home windows 10 can view the information. Fats or exFAT will work.

Pre and Publish-installation software program

Lastly, earlier than we get began we’ll want some software program for creating our set up media. For that, we’ll be utilizing the Home windows media creation device from Microsoft. We’ll want entry to a PC operating Home windows to make use of that.

We’ll additionally want software program for putting in drivers for our Mac Professional in Home windows 10. For that, we’ll be utilizing Boot Camp Assistant to obtain these information in macOS.

What to do

Software program preparation

First, we’ll obtain Home windows help software program that may give the hardware in our Mac Execs higher performance in Home windows 10.

  1. From a Mac, begin Boot Camp Assistant.
  2. From the menu bar choose Motion>Obtain Help Software program.
  3. Select a save location.

As soon as downloaded save the Home windows help information to a community location or a USB drive.

Subsequent, we have to create the set up DVD.

  1. From a PC operating Home windows, navigate to
  2. Obtain the media creation software from Microsoft.
  3. Run the downloaded software.
  4. Settle for the consumer settlement.
  5. Choose create set up media and click on subsequent.

  6. Uncheck use advisable choices for this PC and click on subsequent.
  7. Choose ISO File and click on subsequent.
  8. Select a save location and click on save.
  9. As soon as accomplished downloading, click on open DVD burner.
  10. Burn the DVD.
  11. Click on End to exit.

That is all of the software program prep we’ll have to do.

Hardware preparation

Subsequent we’ll want to start out Home windows 10 set up course of from the Legacy BIOS enabled PC. You could have to make modifications to the BIOS settings and every motherboard has its personal configuration which is past the scope of this text. I strongly recommend that you simply take away any put in knowledge drives within the PC and pay attention to any BIOS setting modifications so that when we’re carried out with this step, you possibly can put all settings and hardware again to their unique state. Eradicating the drives of the put in PC will prevent from deleting something by mistake.

  1. Connect the disk drive to be used in your Mac Professional in to the PC SATA cable and energy connector.
  2. Energy on the PC and place the Home windows 10 set up DVD into the DVD drive.
  3. Comply with the Home windows 10 set up course of as you’d usually however one you attain the partitioning step.
  4. If any partitions exist on the drive, delete them right here. Make sure to not delete any knowledge drives you need to hold (it is best to have eliminated them).
  5. As soon as all deleted, create a brand new partition. If Home windows says that it’ll partition the drive in a number of elements then you definitely did NOT boot in Legacy mode. It’s essential to repair your BIOS settings and check out once more. If nevertheless, you possibly can create a brand new single partition and clicking subsequent does not immediate you that there will probably be a number of partitions made. You’ve got succeeded with this step.
  6. Home windows will now begin copying information to the disk drive. When the set up will get to the ending up stage, it’ll immediate you that it’ll reboot. When you see the countdown for a reboot, manually energy off the PC.

Now you can detach the disk drive from the PC and return the PC hardware and BIOS settings again to its unique state. Subsequent it’s worthwhile to place your disk drive meant on your Mac into the Mac Professional.

When you’ve got your unique Mac Professional GPU or a GPU flashed to work with a Mac EFI then you possibly can merely maintain the Choice key whereas booting and choose the Home windows drive in addition from. Should you hav upgraded your GPU that does not present something whereas booting and isn’t suitable with the Mac EFI boot course of you will have to do the next.

  1. Energy off your Mac Professional.
  2. Set up the disk drive you began the Home windows 10 set up on into an empty drive slot. In the event you purchased a 2.5 inch disk, you will want an adapter to maintain the drive safe. I simply rigged my very own fastener.
  3. Energy up your Mac Professional.

Subsequent we’ll set the Mac in addition off of the Home windows 10 set up drive.

  1. Begin System Preferences.
  2. Choose Startup Disk.
  3. Click on the Lock.
  4. Choose the Home windows system and click on restart.

Your machine will reboot into the second part of the Home windows 10 set up sequence. Full your Home windows 10 set up as you’d on any PC.

When you’re on the Home windows 10 desktop, you’ll be able to set up the Home windows help software program in your Mac Professional hardware.

  1. Copy the Home windows help software program out of your community location or your USB drive onto the desktop.
  2. Subsequent comply with these directions on how one can set up Boot Camp drivers on unsupported Macs.

Reboot your Home windows 10 in your Mac Professional and your units ought to now be useful.


As I discussed earlier this can be a much less refined technique with some drawbacks. If you do not have and supported GPU, to be able to boot again into macOS out of your Home windows 10 occasion, You will have to reset the NVRAM upon reboot. This entails holding the P-R-Choice-Command keys whereas rebooting for 2 system chimes. When you hear the second chime, you possibly can launch the keys and you will be introduced again into macOS Mojave.

To return into Home windows, use Startup Disk in System preferences like earlier than and restart.

Resetting the NVRAM additionally resets your SIP settings. So in case you’ve cobbled different system hacks into your Mac surroundings , you will need to keep away from utilizing this technique.

In case you are nonetheless utilizing your unique GPU then as soon as once more, merely maintain the choice key while booting and you may choose your macOS drive in addition from.

Ultimate feedback

That is it. You’ll be able to have a default-as-Apple-intended occasion of macOS on one drive in addition to a totally practical Home windows 10 set up on one other drive. You will not should swap drives when booting between OSs. You will not should disable system protections. You will not have to put in boot managers. You will not should cope with partition managers. You will not need to cope with GPT vs MBR when putting in on a Mac. It is only a a lot easier strategy to get each OSs put in and have entry to the complete energy of your hardware (no VMs wanted). Thats how I do it. Now I might like to listen to about your easier non-virtual machine method within the feedback under.
