Not sure what happened but i do get that same issue but im not sure how to install the software mentioned above to fix that problem. Im not in dual booth and theres now other way for me to access the unit.

however what i did was first turn off the machine,
remove all usb plugged in like the bluetooth, printer and camera, and even the network cable.
and restarted.

it worked after that. and then i plugged all usb and lan back in.

the question if it works the next time.
