The best answer to this is D. If there are incorrect CMO settings, it can already be expected that the fixed disk error will start to appear. When this occurs, you have to open your CMOS setup and to set so that you can make some changes. If you are still not familiar with what the CMO is, this is used to describe small details that can be seen in the motherboard of your computer.
If in case you do not know how to fix this, you can always hire a professional to change and improve the settings for you. Once this is set, you will not see the error message anymore.
