    Umounted Boot Volume


    I have a Toshiba Laptop, windows 10 I turn it on as normal. It starts up and then comes up with:


    Your PC ran into a problem and needs to restart. We’ll restart for you.

    Stop Code: unmounted Boot Volume.

    This is all before the log in.

    i have no access to cursor or keyboard. It just keeps restarting and saying the same thing.

    :)
