Hi, mubz, Thank you very much for joining the Intel® Desktop Boards communities.
The configuration you are using should be recognize by the BIOS, so I just wanted to gather some details in order to better assist you:
Could you please provide the model of the hard drives and the DVD drive?
Which ports on the board are you using to connect those 3 devices?
Please set the BIOS to defaults by pressing F9 and then F10 to save the changes.
We can try a BIOS update to the latest version, on the link below you will find the instruction of how to do it and the .BIO file needed, 0160:
Any further questions, please let me know.
