This is now beyond a joke. My Toshiba laptop has been stuck in restoring to previous version for 2 months now. I have tried ALL the suggestions on this thread and none of them work. The only thing I have been able to do is press F2 and get to Utility screen. Pressing F8 doesn't work. I have gone out and bought a 16GB USB stick (so I have enough memory) and have downloaded the creation tool but cannot do anything with it as my Toshiba is consisently stuck in RETORING TO PREVIOUS VERSION LOOP.
I cannot believe that Microsoft STILL have no better solutions other than continually repeating the same processes which they have been told repeatedly on here that THEY DO NOT WORK IF WE CANNOT GET PAST THE RESTORING LOOP SCREEN!
Come on Microsoft, get your head out of your ass and FIX this problem as YOU created it!
