I hope someone can help. W10 (64 bit Home) has been working OK on this laptop but recently I have been able to open the settings screen for only a micro-second. Having found people having the same problem I have tried running SFC several times, as suggested, but it says it found an issue it could not resolve.
Again following instructions on the forum I tried running DISM with an iso loaded and this hung at 40% for hours (overnight). I could not find a solution to this, but someone posted their CBS log and was given a solution to the original problem.
I do not understand what to look for in the log file, but there are several lines that mention an error. I attach the log file (zipped as it was too big for the forum), and if anyone can help I would be grateful.
