    • I have the same problem. Bought the new yoga 13, set it up an then went on holiday for 2 weeks – I cannot remember my password now! Did u solve your problem? Or anyone else have an idea?

    • HI Joe, you may try different password recovery / bypassing tools. Any password bypassing tools, working on Windows 7 can be used here.

  2. Ok i have a problem,i accidentally turned my laptop off while it was resetting,so i cut it back on the next morning,and it said to reinstall windows.
    How can i when it wont let me go anywhere else but to the same black background,telling me over and over “windows is not installed press Ok to restart”


    • If you have already made an USB recovery, you can use that to get back your proper system image. Otherwise do a clean installation of Win 8 using USB or DVD.

    • Hi Duke,
      If you are using Windows 8.1 please select Settings > Update & Recovery > Recovery and then select Refresh or Reset option

  3. The Refresh or Reset option prompts me for a disk. I am near desperate to get rid of 8.1 and go back to 8. But my recover disks have disappeared. What can I do??

  4. I followed your directions but was advised the missing files I required were on my installation disk. I don’t have an installation disk. I thought this method resolved that problem. Not so much.

    • Hi John, if some important system files have been deleted from your system, then you may need to have a recovery image or installation disk to repair it.

  5. I followed your methods but I it says some files are missing. Windows installation or recovery media will provide these files. What should I do?

  6. pls helpme with my laptop full menu is gone and everything is just a mess someone said it needs to be reloaded so can you pls help me reload it pls
