Q: No boot - WIndows does not start - blk screen

Sep 29, 2015 10:22 AMby Loner T,After the initial Win7 installation, have there been
1. Any OSX Updates?
2. Any Windows Driver Updates?
We can pick one Mini and analyze it further. Can you post the output of the following Terminal commands?
diskutil list
diskutil cs list
sudo gpt -vv -r show /dev/disk0
sudo fdisk /dev/disk0
The "sudo" commands will prompt for your password, and it will not be echoed back. You may also see a warning about improper use of "sudo" and potential data loss due to "abuse" of the command.

1) NO OSX Updates during the use
2) I do not know but I don't think so.
In the first MacMini I managed there was a CoreStorage volume; I deleted it in order to format the Hard Drive and try a complete new installation of macOSX and then bootcamp.
I installed a NEW 10.10.5 and I started again with the BOOTCAMP procedure BUT, during the restart to load the WIN 7 OS ( file from a pen), the Mac stopped to work as usual.......
MacMini sees the WIN7 disk ( and also a usb stick ) as bootable BUT when it tries do execute it, it stops.
Last but not least: macMini in target mode, loaded as hard drive on my mac ( I have NTFS extension on it ) and repaired as NTFS volume; nothing changed.
I suppose there is something wrong into the firmware......this is my opinion...... because 2 times it started but it freezed during the installation procedure
( for the command you asked me, I need to go to customer's place and I'll post the result later )

Oct 3, 2015 2:30 AMby Roberto Ballabeni,Loner I have the MacMini.
An Update: I wanted to try with Genius bar and, as aspected, they did not find any solution.
I noticed one thing: the firmware installed on it IS NOT the one listed into Apple's web site.
This is the one listed: MM71.0220.B03 (2015-001)
In real the installed is .B05
Apple Care told me to use El Capitan because "it contain all WIN drivers"; I tried but, of course, there is NO driver installed and the suggested WinOS is Windows 8 hahahahahahaha
OK; what are your suggestions?

Oct 4, 2015 9:06 AMby Loner T,1. Can you verify that the USB flash drive is
a. a USB2 flash drive,
b. is directly connected to the Mac
2. There are multiple USB ports. Can you test with all of them? I suggest a SMC Reset/NVRam Reset before each post is tested.
3. The Intel GPU drivers are the suspect, as far as I am concerned.
