Hackintosh Dual Boot Windows 10 and macOS High Sierra (Same Drive)

On a hackintosh it’s possible to dual boot macOS and Windows on the same hard drive disk, which I will explain how to here. Although it’s recommended that macOS be installed on a separate drive than Windows, it’s perfectly possible to dual boot Windows and macOS on the same drive for those that don’t have multiple hard drives to spare.

Dual-booting on separate hard drives is super easy you just install macOS on one drive and Windows on the other and then simply boot Windows as a temporary device or through the Clover menu. For those that want to install both macOS and windows on the same drive this guide to walk you through the steps.

Hackintosh Dual-Boot Guide

For those of you not familiar with dual-booting or a macOS hackintoshing. We will first need to format the drive as GUID using Disk Utility. Disk Utility is an application in macOS that is basically the equivalent of Disk Management in Windows and can be accessed in the same way Disk Management is either during the install or in the operating system after installation is completed.

The drive should to be formatted first in macOS Disk Utility as the GUID format is required to install macOS and doing it with Disk Utility will also create a larger 200MB hidden EFI partition, which is larger than what is created with Windows Disk Management (100MB) and will therefore be able to fit both the macOS and Windows EFI files as well as leave some extra room left over.

We can either make the Windows partition during the install or after the install. The reason you would want to do it during the install is if you wanted to have the Windows partition show up as first and the macOS partition as second, however personally I prefer having macOS first and Windows second as my hackintosh is reliable enough that I use macOS almost exclusively.

For Dual-Booting the only requirement is that the SSD/HDD be first formatted as GUID. You could install Windows before macOS if you really wanted to, but  for this guide it makes sense to install macOS first and then Windows second as we already have to be in the macOS installer to format as GUID and don’t have to move anything around in the EFI with Windows installed after macOS.

Step 1: Access macOS

To create a macOS flash drive installer you will first need either a. Access to a Mac or b. A virtual machine running macOS. If you do not have a Mac or borrow then create a virtual machine running macOS using one of the two links below depending on whether you are using Intel or AMD as your CPU/Processor.



Step 2: Make a macOS High Sierra Hackintosh

Now that we have access to macOS we will now create a flash drive installer containing macOS install files and then install macOS. Based on what CPU/Processor you are using following the full guide below and then return to this one once you have macOS running. Just os you know you will need to completely wipe the drive you are using in order to format as GUID using Disk Utility. Also after macOS keep the flash drive the way it is as you will need it later. You will need another separate flash drive to install Windows if you don’t already have an installer.



Step 3: Create a Partition for Windows

Now that we have macOS installed it’s time to make some room for Windows.

  1. Open Disk Utility
  2. Select Show All Devices by clicking on the View button at the top left corner of Disk Utility
  3. Select the Drive (The drive is name of the drive like Samsung/Crucial and is indicated by the arrow to the left of it’s name)
  4. Click Partition button at the top toolbar
  5. Add a new partition by clicking the [+] button under the circle
  6. Give it a name and desired size I would give a minimum of 50GB for Windows 10
  7. Set Format: ExFat
  8. Click Apply

Step 4: Install Windows 10 on Hackintosh

If you dont have a way to install Windows you will need to create USB flash drive with Windows on it, but don’t wipe and use the same flash drive you used to install macOS as you still need that to regain access to macOS in Step 5.

  1. Download Windows Installer Manager/ISO
  2. Create your installer
  3. Boot the UEFI: partition of the Windows Installer (Note: Very important that you boot of UEFI: partition of the flash drive otherwise you will get a GPT error and the “Next” button will be greyed out)
  4. Go through the first parts of the installer and select Custom: Install Windows only (advanced) when you reach that step
  5. Select the Windows partition you created in Disk Utility
  6. Click Format
  7. Click OK when the data lost prompt appears
  8. Complete the install… Note: System will restart multiple times during install

Step 5: Cleanup EFI & Regain Clover Access on Boot Drive

When finished messing around in Windows it’s time to jump back into macOS. To do that we are going to using that macOS flash drive installer that you should have kept as a backup to boot back into macOS. The reason we can’t use the drive macOS/Windows is installed on to boot macOS is because the Windows installer modified our EFI folder overriding Clover Boot loader with Windows Boot Manager causing the UEFI: (your_drive_name) not to show up in BIOS boot devices or in the temporary boot device menu.

There are a couple different methods to a fix dual-booting hackintosh using only one drive for both installs. It’s done by messing around with various .efi files to get dual-booting working. I’ve tested a couple different methods and this one below is the easiest.

To fix our dual-booting hackintosh we need to deal with a file called bootmgfw.efi which is preventing access to Clover at system boot. All you need to do is rename bootmgfw.efi to bootmgfw-orig.efi causing Clover to become unblocked. We add the tag -orig to the name so that it’s still recognizable file and will show the Windows EFI partition for booting in the Clover Boot loader Menu.

To rename bootmgfw.efi:

  1. Boot off the UEFI: partition of your flash drive macOS installer
  2. Boot macOS drive
  3. Open Clover Configurator
  4. Select Mount EFI on left column
  5. Click Mount Partition for the drive macOS and Windows is installed on
  6. Click Open Partition
  7. Navigate to EFI/Microsoft/Boot/
  8. Rename bootmgfw.efi to bootmgfw-orig.efi
  9. Restart and UEFI: (your_drive_name) should be an available boot device

(Optional) Override Windows Boot Manager

If for some reason UEFI: (your_drive_name) isn’t showing as an available boot device there is a way to override Windows Boot Manager and have it redirect to Clover. To do that first boot macOS off your flash drive again.

  1. Mount the EFI partition of your boot drive using Clover Configurator again
  2. Open the EFI and navigate to EFI/BOOT/
  3. Copy BOOTX64.efi
  4. Navigate to EFI/Windows/Boot
  5. Paste BOOTX64.efi here
  6. Rename BOOTX64.efi to bootmgfw.efi after pasting
  7. Restart and boot off Windows Boot Manager and you’ll notice it redirects to Clover instead of booting Windows (Pretty cool huh?)

Step 6: Dual-Boot thru Clover

You can now use the Clover Menu to boot Windows.To do that select Boot Windows EFI from EFI in Clover.

You are now finished congrats!!!

I keep getting stuck at step 4.5 . Although I’ve done everything accordingly, follow the GUID Partition map, Format the drive as Mac OS Extended Journaled, the PC wouldn’t allow me to choose that drive to install Windows on. It says on the screen that “The selected disk is of the GPT partition style. Windows must be installed to a partition formatted as NTFS. The partition is of an unrecognized type”

Look forward to getting some advice from admin and members of hackintosher. Thanks


Just a little correction …
On my particular windows 10 usb,
I needed to boot boot64 file from the EFI directory / folder.
It isn’t a separate partition.
If this is true for all windows 10 installers, i don’t know.


Important !
There is a possibility that users need to repeat Step 5,
If there is a major Windows Update.
( which probably happens often, lol )

Hey! Thank you very much for all the guides, I followed nearly everyone lol. But I finally got the Hackintosh working, then I installed Windows, and bang, black screen, I tried again with your guide of reinstalling the Nvidia Web drivers, and all come back. Really happy now bc I have both macOS and Windows running stable. Thank you very much!

Thanks for the guide! However, I keep running into a snag. I formatted the windows partition as ex-fat and attempted to install, but once I do the installer prompts me to restart the install again….(no progress at all). I’ve tried to format the partition in other formats, such as Mac OS journaled and fat32, but that hasn’t worked either. Any ideas?
