Recently built a new pc, specs are as follows
Fx 8320
Zotac 780
212 evo cpu cooler
8gb corsair ram 1600
1tb hdd 7200 rpm
Asus m5a97 le r2.0 mobo

My problem is that when it was all hooked up correctly and was booting into the efi bios, it flashed me a message saying that "The current BIOS setting do not fully support the boot device."
"Go to advanced>CSM parameters, and adjust the csm settings to enable boot device".
What do I do?
Also my other problem is that when boot priority is shown, theres nothing there. No hdd, cd Rom, nothing. Both have sata cables connected to them, and I know the disc drive works because it opened. Please help.
P.s sorry for the long report.
