Currect BIOS setting do not fully support the boot device?

[Tezalus]

I recently bought an updrade package for my computer and installed Windows 8 on my old HDD on top of my old Windows 7 and later deleted the the old Windows files. My computer starts without problems when I press the power button but if I restart or press reset this message comes up:

"Currect BIOS setting do not fully support the boot device"

"Go to advanced -> boot -> CSM parameters, and adjust the CSM settings to enable the boot device"

This is very strange to me since it worked before and I've already checked that my SATA drive is enabled. I'm afraid I don't understand much of the advanced settings in BIOS though, so how can I fix it?

This is my new hardware:

ASUS M5 A97 R2.0 motherboard
AMD FX 8350
8 GB RAM (doesn't really matter)

1) Make sure there is not any disc in the DVD drive.
2) Make sure your hard driver with win8 connector to the 1st SATA port, usually it will be labeled SATA_0 or SATA_I, not the SATAG ports, check your manual.
3) Or check the link for about Secure Boot is Enabled http://www.eightforums.com/tutorials/20208-secure-boot-confirm-enabled-disabled-windows-8-a.html
4) You can even try go to the BIOS set to the bios settings to default.

1. I don't have a DVD plugged in.
2. My hard drive is plugged in to port 1.
3. Secure boot is unsupported.
