"The current BIOS setting do not fully support the boot device"

[786aboy]

I just purchased a new CPU to play a single game and that is battlefield 4.
yesterday while playing it didn't gave me any problem but today when i was playing it in the morning it suddenly get stopped and kept saying that Your Current Bios do not full support the boot device.
"Go to Advanced > Boot > CSM Paramters, and adjust the CSM settings to enable the boot device"
I think my BIOS version is 4.0.2
Don't know what is wrong with it and i also am a noob at hardware things or software too. But any help would be appreciable.

Whenever i am restarting my PC this dialogue box is coming up. It didn't even reach the windows screen.

So enter the BIOS by spamming the DEL key as you start the computer .

Setting to optimized defaults should work , but you could also look through the pages and make sure the drive with windows on is the first boot device

Did that but didn't worked i pressed f5 on every option going to every single tab in the BIOS screen but it still is giving me the same problem.

Basically you have two types of hardware devices.

Legacy and Uefi enabled hardware devices for compatibility.

In your bios of your motherboard pressing the delete key, or the key it states on the main display it can be F1 or F2 also.
Tap that key when you first power your system on.

You will see, or enter your Bios of the motherboard.
If it is a Uefi enabled bios motherboard, there will be an option on the main page to select, Advanced bios mode.
You need to select this mode.

Where your boot devices heading is, or advanced options.
You will have a mode called CSM mode. set it to enabled and manual.

The option you want to set is legacy devices OP rom / Uefi devices detection.
Save the new settings or changes before you exit your bios ok.

I don't have to select one. But the option which is showing both of them. Actually that one is already selected. It still is not working
