Updating the Intel Rapid Storage Technology Driver (IRRT) solved my problem - I hope this helps someone else, Ian
I have a Latitude E6230 running Win 7 Pro 64 bit that I purchased recently (used machine). The previous owner re-installed Win 7 and MS Office 2013 but reported that the OS will not update to Service pack 1.   I connected to the Dell website and carried out the full connected machine scan and uploaded the latest drivers and Bios.   All checked out OK but  I still get error code Oxc8000247 and cannot update Win7 with updates or SP1.  I am now at a loss on what to try next, I am a bit reluctant to re-format the drive and start from scratch as I do not possess the MS Office 2013 CD to re-load it. Any ideas? Thanks - Ian
