Discussion SSD not detected in BIOS nor in device manager nor in disk management

[Rajiv Biswal]

I bought new Crucial MX500 SATA SSD for my lenovo z50-70 laptop. I want to use both HDD & SSD together. I have successfully install original HHD in cady & SSD in place of HDD & boot my system but after the SSD is not detected anywhere. I have an updated BIOS. I checked in BIOS menu its not there.I run windows diagnostic, try to use ssd via SATA cable still no luck. What did I miss?
Did I have to replace crucial MX500 with lower version? Do I have to install somethng else? Please help me on this? Thank you in advance.
