AHCI BIOS not installed

Hi,

I woud like to know how to fix this BIOS error. I've tried to change settings and updated BIOS and the error won't go away.

What settings have you tried to change?

Have you tried choosing the default settings?

I suspect that this error is a red herring, as @xrobwx71 pointed out, which settings have you changed? What is the BIOS version you have installed and for which motherboard? I assume that the disk you're having a problem with is SATA-based?

Yes, I tried the default settings, changing BIOS settings like clearing event logs, power the system off and remove the power cable from the back of the system, then hold the power in button for 30 seconds, disable diskette drive, allow sata 0 and 1 drives, uncheck usb floppy drive. I updated BIOS from A16 to A17, and A18 consecutively. The system is a dell precision T7500
