While working with Win 10 under Parallels 10 (and now 11), Windows launched with a black screen. I have looked at the suggested solutions here and they all start with start Windows in Safe mode, which requires a change to the Boot Order screen. That screen cannot be changed until the vm is suspended. When I shut it down, the screen goes away so I can't change the boot order. Also I don't have an .iso on a DVD as the Win 10 .iso that I have is larger than 5 GB. I instead have the Win 10 setup on an 8GB USB, which is what I installed it from. I tried to run setup.exe from that hoping that I could repair Windows and all I got was a black screen. I apparently have to kill parallels to suspend the virtual machine to make configuration changes, but this kills the configuration dialog. Any ideas that hopefully will allow me to run Windows without completely destroying the configuration?
