How do I fix this problem?
This message means that the internal drive is not found.
To check if the drive is broken, remove the drive and try to use it with another computer. E.g.. plug in in as an extra drive in a desktop, use an external USB case or use a HDD dock like these:
To try to solve the middle problem, remove the drive from the laptop and reconnect it. This is called 'reseating the drive`.
If the drive works fine in a dock or in another computer then it is likely a problem with the laptop. Try using another drive and see if it also fails (it probably will give the same problem) so you can confirm this. If it is then check if the laptop is still under warranty.
If you haven't used the machine before, and it is causing this kind of problem, you should return it to the seller.
