Hi Roy

Just for the sake!

I think it's link to UEFI and windows 7 after firmwares updates
The tech said that Installed win 7 on a UEFI (GPT partition) was a very bad idea
Is it possible that an update have switch ON my secure boot I'am (UEFI)???
I remember on the log of MGADIAG tool APCI and ACPI, AMI, HPET... there are link to the BIOS (UEFI)
When i'd tried to do a clean install the error " The system found unauthorized changes on the firmware, operating system or UEFI drivers " at the end i'd turn all UEFI things OFF and Re-installed win 7 on NTFS partition and it's work. Finally i had update to win 10 with the Mediacreation Tool for Win10.

Thanks Roy for Ur time!
