Today I started updating my Windows 10 Professional to Threshold 2, but it started restarting all the time, I can't start up the PC. I tried from the Grub2 menu the option "Windows Recovery Environment" and from there the option sfc /scannow in the command line but I got the response: "There is a system repair pending which requires reboot to complete". I am dual booting with Ubuntu.
I am now downloading the Windows 10 ISO from here. What can I do to repair Windows 10 ? Or even better how can I repair Windows 10 ?
