Mar 20, 2019  How to install Windows 10 on your Mac mini with an external drive Need to run Windows natively on your Mac mini but can't partition your disk? Here's one solution! Drag and drop the WindowsSupport file we downloaded from Boot Camp earlier into the Windows 10 VM window. Install Win-to-USB in the Windows 10 VM.

If your Mac has an AMD video card and is having graphics issues in Windows, you might need to update your AMD graphics drivers instead.

  2. Plug the USB flash drive into your Mac.
  3. Open Disk Utility, which is in the Utilities folder of your Applications folder.

  6. Click the Erase button or tab.
  7. Choose MS-DOS (FAT) as the format and Master Boot Record as the scheme.
  8. Click Erase to format the drive. When done, quit Disk Utility.

Install the Windows support software

After downloading the Windows support software to your flash drive, follow these steps to install the software. (If you're attempting to resolve issues with a Bluetooth mouse or keyboard, it might be easier to use a USB mouse or keyboard until these steps are complete.)

  1. Make sure that the USB flash drive is plugged into your Mac.
  2. Start up your Mac in Windows.
  3. From File Explorer, open the USB flash drive, then open Setup or setup.exe, which is in the WindowsSupport folder or BootCamp folder. When you're asked to allow Boot Camp to make changes to your device, click Yes.
  4. Click Repair to begin installation. If you get an alert that the software hasn't passed Windows Logo testing, click Continue Anyway.

If you can't download or save the Windows support software:

  • If the assistant says that the Windows support software could not be saved to the selected drive, or that the USB flash drive can't be used, make sure that your USB flash drive has a storage capacity of at least 16GB and is formatted correctly.
  • If the assistant doesn't see your USB flash drive, click Go Back and make sure that the drive is connected directly to the USB port on your Mac—not to a display, hub, or keyboard. Disconnect and reconnect the drive, then click Continue.
  • If the assistant says that it can't download the software because of a network problem, make sure that your Mac is connected to the Internet.
  • Make sure that your Mac meets the system requirements to install Windows using Boot Camp.

If a Mac feature still doesn't work after updating the Windows support software, search for your symptom on the Apple support website or Microsoft support website. Some features of your Mac aren't designed to work in Windows.

Apple is trying to get us to dongle attach 'all the things' but what happens when that philosophy doesn't jive with all of your computing needs? One such situation is when wanting to run Windows 10 natively on your Mac (in my case my Mac mini). The 'normal' method would be to use Boot Camp to repartition your internal hard drive to make room for Windows 10. However, in some instances, repartitioning may not be an option. For example due to disk size limitations. Attaching a Thunderbolt 3 connected drive is the obvious solution but Windows 10 does NOT like to be installed onto detachable devices. Here's how to force the install of Windows 10 onto your externally attached drive!

What you'll need

Mac Windows Boot Camp Drivers

Hardware

Of course you'll need an externally connected drive. I went with a 240GB SATA SSD ($30) that I placed into Thunderbolt 3 capable external SATA enclosure ($9).

Install Win-to-USB in the Windows 10 VM

That's it! Once the machine reboots you'll be presented with a Windows 10 install sequence. Follow the prompts like you normally would and you'll be able to run Windows 10 natively on your Mac. Here are some notes to follow up on.

  1. Once your windows installation is complete, remember to navigate into file explorer and install the Boot Camp drivers for your machine. That will setup your network card, display, and other Apple-centric devices. This will also install the Boot Camp program to help you reboot into macOS.
  2. If for some reason you have troubles, power down your Mac and simply detach your external drive. You should be able to simply reboot into macOS.
  3. If that fails, hold Command-Option-P-R all at once and wait until you hear two chimes. Once done, you'll be able to boot back into macOS.

Final comments

Now you can run native Windows 10 and native macOS Mojave. The best of both worlds with little compromise. If you have any tips on getting this working in a better or faster way. Please let us know in the comments!
