    Unable to disable Secure Boot in Windows 7 (New MOBO)


    Hello. I recently bought an Asus P8B75-M LE along with an MSI GTX 660 Ti OC V1 and an i5 (My OS is Windows 7 Home Premium 64bit). Every time i start the computer i get this message: "The current BIOS setting do not fully support the boot device. Click OK to enter BIOS Setup" and a yellow text: "Go to Advanced > Boot > CSM Parameters, and adjust the CSM (Compatibility Support Module) settings to enable boot device.". I've tried for hours, but to no avail. I've updated the bios to the latest version, too. But i believe i know what the problem is. I need to disable Secure Boot, but the option to do so is greyed out. The only option i am able to change is "OS Type". Please, help me! I'm getting really frustrated here.

    I've read it. It still doesn't work. Also, i've got no boot options. The "Boot Priority" list is empty. Do i need a Windows 7 CD? (Before you start flaming me, this is my first time doing this.)

    Have you looked at the manual that come with the motherboard?

    From your manual.

    Get a paper clip and poke it in the hole on the DVD slide.
    The DVD drive will open whether the machine is on or not
