When you try to Upgrade to Windows 10 from a previous version or to upgrade to the new November version (10586) and you have the system partition encrypted the system will start the setup and reboot, but after the reboot sends you to the troubleshooting screen and restarts again and gives and error 0xC1900101 – 0x20017 on SAFE_BOOT.

The solution I found to this issue is to decrypt the drive, upgrade and then encrypt again.
