Precision 7540

Good day Dell Community, I have just bought a Precision Workstation 7540 from Dell. I have ordered it with a SATA 500 Mb hard drive knowing I have a 4 Tb SSD in my actual Precision M4800 I wanted to use. I have tried everything I know but the Precision 7540 cannot see my Samsung SSD 860 Evo 4Tb in the BIOS ??? Any idea of what might be the problem ?? I have updated the BIOS to the latest version. Thank You in advance. Richard
