I've tried to run the SFC /scannoow twice and both times I get to 7% and I get "Windows Resource Protection could not perform the requested operation". I had this once before and resolved it, but I can't remember how. I've ran chkdsk twice and I still can't get past 7% on sfc/, so it appears running chkdsk was not the solution. I'll try and post the logs here so you can see if there's anything I can do to get the sfc/ to run ful 100%. I can't seem to add this log file as an attachment from the cbs logfile so unless this is needed someone will have to give me a heads up on how to post this to this thread.
