15 R3, Bios not detecting third HDD, Boot Device Not Found

Dear all, good day. Any expert can help ?

My laptop is Alienware 15 R3, it showed "Boot Device Not Found". I checked Bios and found Third HDD is missing in Bios (only Forth HDD is there) , please see below screen: 

I used Diagnostic function after pressing F12 and found the third HDD can be found together with forth HDD using Diagnostic , but current Thermals of third HDD is "n/a", please see scree below (BTW, all components including third HDD show "ok" after Diagnostic):

Is there anyone who could help me to make my laptop back to operation, thank you so much in advance.

Best Regards,
