Windows 10 1803 doesn't start on Boot Camp

Hello,

I'm running Mac OS X High Sierra (10.13.5), and I require a Boot Camp partition for my work.

I've been able to successfully install it, using ISO from Microsoft with version 1803, and the first boot worked like a charm.

As I have Fusion Pro, I use it to start my Boot Camp partition as a virtual machine, and that works well too.

But, unfortunately, when I try to boot on Windows 10 (alt key at boot and select Windows), I have a black screen and then the login screen of my Mac...

I've also looked at Startup Disk and the Boot Camp partition doesn't show.

I've tried a complete reinstall (MacOS and Windows 10) and I have the same issue.

Any idea ?

Thanks
