So it turns out everything had been installed and partitioned correctly, and my Mac mini was booting into the new Windows boot partition, but using HDMI output! So the black screen I was seeing was because it was outputting the display to HDMI, not my VGA monitor via the display port adapter.
It's important to note that it's obviously a damn good idea to remove other USB devices from the system during this process, or it may boot and pick the wrong USB device.Īnyway back to the black screen.
The boot partition is part of the partition that the 3rd tick box does in BCA, which seems to tell the Mac 'use this boot loader (EFI) in the partition I created, and use for the USB disk you just created for the install files' - so it purely uses the USB as a storage device for the Windows install. When my computer rebooted for Windows it was simply going to a black screen so I figured the USB boot wasn't working. In the process I think I've understood a lot more about how my Mac Mini (Late 2014) boots now for Boot Camp.įirst, I thought the USB stick it prepared (I was using Windows 10 Preview ISO) was the actual boot device. I'd been battling all night thinking there was issues with my USB stick etc or some weird partitioning problem etc. Just another possible answer for anyone else with a similar situation to mine.
