Question

Help! I turned on my computer and this screen came on out of nowhere, I don't know what to do to fix it.

Answer 1

Your boot device is corrupted

Explanation: Please use startup repair if you have data on hard drive ,if data is not problem please reinstall os .

Answer 2

Here are the steps I would do:

Do a "hard" power off. Hold the power key until the screen turns off. Wait 10 seconds. Turn it on. If it still shows the screen... then i'm not sure.

The error is occurring because it has nothing to boot off of. It's probably something wrong with your hardware. The instructions say for you to insert a "boot disk" and press any key.
