i have been scrolling and trying most of the solutions for resetting my ultrabook to factory settings - nothing has worked to this point and it seems to be getting worse. now after pressing 0 and the power button i am getting the following message:
Reboot and select proper Boot device
or Inser Boot Media in selected Boot device and press a key
Yes...i did try this but once i hit the power button to turn on the laptop, it goes directly to that reboot black screen and i have held down the 0 button continuously and never makes a beeping sound even after 3 minutes...
