When I restart a 2nd, 3rd, etc. time its normal again until the next day.It takes a break for ca. 1 min at this point:and at this point: Link to comment Share on other sites More sharing options...
Administrators Hervé Posted April 14, 2017 Administrators Share Posted April 14, 2017 I see reports of errors on your NTFS partition so you may want to watch out for HDD errors. Then, there is clearly a timeout with your Bluetooth device. Maybe you need to repatch a kext or re-apply a firmware patch. Difficult to say more until you advise on the hardware model....

Karl V. Posted April 14, 2017 Author Share Posted April 14, 2017 Would it be useful to reinstall these kexts (SLE_optional) from your Sierra-Pack # 3? Tonight, the Windows partition did not cause any trouble ... maybe tomorrow again Link to comment Share on other sites More sharing options...
Administrators Hervé Posted April 14, 2017 Administrators Share Posted April 14, 2017 Then I suspect you might have a dying HDD... Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted April 14, 2017 Administrators Share Posted April 14, 2017 windows should be completely shut down/ powered off before starting or restarting your bootloader Link to comment Share on other sites More sharing options...
Karl V. Posted April 19, 2017 Author Share Posted April 19, 2017 Today I could not get anything to boot... no Sierra, no backup partition, no Windows ...But now my hackbook seems to run perfectly again - the solution to the problem: I killed Windows10 !
