Why doesn't my computer BIOS detect my new SATA Drive?

I had this SATA drive in an external drive for storage, but wanted to put it in my puter as the main drive due to the older drive was having intermittent problems. So I cloned the old drive to the SATA-no problem. Installed in pc and it works but in the BIOS it is not detected! I still have an IDE drive as the slave(has always been the slave). In disk management, it shows both drives and has the IDE as the master......What do I need to do to overcome this problem? Any help would be greatly appreciated.

 

You should probably set the IDE drive to either Master or Cable select, if it's the only drive on that ribbon cable. Is there a setting in your bios for SATA compatiblity mode/Native or something along those lines?
