The process ihas failed twice in the same place at the end of the process with the message: We couldn't install Windows 10 We've set your PC back to the way it was right before you started installing Windows 10. 0x8007001F - 0x20006 The installation failed in the SAFE_OS phase with an error during the REPLICATE_OC operation. Click to expand... I have followed Windows Update Forum Steps #1 to #6 methodically, run sfcfix, and placed the CBS.zip file in Google Drive. Thank you for your assistance to review the log files.
