Aurora r4 Internal hard disk drive not found error

Hello.

Iv been having problems with my command center controlling my fans and after looming into it I removed and reinstalled command center and updated to the latest bios. I tried to install a11 bios which told me I need a05 first. A05 installed fine I then installed a11 but when it rebooted to finish installation nothing happened. All the fans went to max speed and that was it for about 10 minutes until I gave up and held the power button down to turn it off and try reboot. It started and the fans we're normal but it only got as far as the internal hard drive error . I ran the diagnostics which said my hard drives we're fine and there was no problems but it still keeps giving me the error every time I try to boot. I tried changing settings in the f2 setup thing. I set the hard drive as first boot device. I dont know what else to try. Any ideas?

Thanks
