Spot on...and the reason for such a dual boot was I used my M$ Account to be able to dual boot and retain all my setups.
This all worked perfectly from the first preview in OCT untill preview 10130 when M$ updates caused the locked drives.
Having rectified the locked drive as described earlier everything worked as normal until I installed 10147 and installed updates.
It appears to me that M$ locked the drive, ie- two systems using the same drive is not au fait, which is of course their way of making sure that only bona fida qualifiers could obtain the update.
I must admit also the above experiment was made hopefully after W10 is released to the general public, to be able to retain my copy of W8.1 and at the same time remain in the W10 Preview with a dual boot.
This I believe now is not possible.
My original post on the subject was to help a member who appeared to have the same problem as myself.
Mystere not having had himself experienced this problem, made suggestions which were completely irrelevant, and finished off by stating he could not understand what i was trying to say, such a shame to use such a demeaning statement.
