Hi guys, Teething problem. My macbook retina 2015 is upgraded to Sierra 10.12 and now 10.12.1 Beta. It is bootcamped with Windows 10 just 10 months ago. All is good till recent windows upgraded to Version Anniversary 1607 and all hell break loose. I lost my ability to boot to windows and it always end up rebooting with unrepairable error acpi.sys I have since reinstall the bootcamp and its worst. Whenever the Windows installation passes the bootcamp installation. Same problem occur again. Though i can boot up windows 10 (WITHOUT the bootcamp control panel) and install back all my stuffs, till i tried to reinstall the bootcamp.exe again., unrepairable error acpi.sys occur again. Please help me.
