Black screen at restart with Boot camp

I have searched the forum for bootcamp problems and found that the problem I'm experiencing was already discussed here.

I have the exact same mac mini which is connected via thunderbolt (displayport) to my monitor.

In my case I'm trying to install Win10 64 Home full install via a USB drive.

The boot camp assistant performs all three tasks without any problems and then proceeds to restart the computer.

At that point the screen remains black. I look at my USB drive and no activity appears.

I already tried to use the alt/OPTION key at restart but nothing appears.

Following the recommendation from Loner T in the aforementioned discussion, I've already loaded the display drivers from the Bootcamp Support Software 5.1.5621 in the $WinPEDriver$/IntelVBGraphics64 folder in my USB.

Nothing changed. Even tried an HDMI connection to my monitor with no success.

I believe it may be an issue with the Intel Iris Graphics drivers but cannot be completely sure.

Any help or suggestion would be greatly appreciated.

Mac mini, macOS Sierra (10.12.2)

Windows Update on W10 is notorious for providing bad drivers. I suggest disconnecting the Mini as the installation starts, and fully install Windows, create a Windows System Restore point and then use https://support.microsoft.com/en-us/kb/2500967 to disable specific drivers. Disable the Iris driver from updating, at least.

What is the version of Windows you are trying to install?

In most cases, TB is not supported, because these drivers are installed after Windows is fully installed.

You can either use HDMI or a HDMI-to-DVI/HDMI-to-VGA adapter.

Thank you for the prompt reply.

Windows 10 Home 64 bit (downloaded iso from the MS website).

Ok. I already attempted a restart with the mac mini connected to my monitor via HDMI. But no display. After awhile it just boots into OSX.

So, if I understand you correctly, do I need to run the Boot camp assistant and prepare my USB drive with all the necessary windows files WITH the Mac mini connected to my monitor via HDMI and not TB?

Just tried it again, finally a display.

Thank you again.

One question: should I let windows update operate as normal and let it update the minis drivers ?
