Samoréen 8 Posted December 8, 2016 Share Posted December 8, 2016 Hi, I'm unable to upgrade my Windows 10 to the Anniversary version and I'm always getting the following error : 0xC1900101 - 0x20017 "The installation failed in the SAFE_OS phase with an error during BOOT operation". I have been told that this could be due to my AV locking or writing to the SRP (System Reserved Partition). Is it actually the case ? Thanks in advance.
