" No Hard Disk Detected After Flashing Bios "

I have Vista Home Premium 64 bit OS and I flashed the Bios using my A1 Suite in Asus to upgrade it and everything went fine but as can sometimes happen I got the message upon reboot that " No Hard Disk Detected ".

Everything is working fine from bootup to shutdown and I know that there is a fix for this...I think in the Bios...but I forgot what it is. Any and all help is very much appreciated. Thanking you all in advance!

My specs are as follows: Mobo is Asus P5Q3 Deluxe WiFi-AP @n LGA 775 ATX Mobo, Intel P45 Chipset, Supports Intel Core 2 Quad CPU's, Dual DDR3 2000, Sata 3Gb/s RAID, CrossFire Ready, PCI-E 2.0

 

Have a look in your BIOS settings 'Standard CMOS Features' and look to see if your hard drive is set to 'Auto'
