Just installed WD Blue SN550 ssd in Dell laptop. Not being recognized

Hello all- i recently purchased a WD blue SN550 s50gb SSD for a Dell Latitude 7470.

I installed it and it fit in fine. i screwed it in and started the computer. I first was trying to install Win10 when i kept getting this error

when trying to install it. then i restarted the computer to the bios and noticed the SSD is not under the boot options! i tried switching to legacy and restarting again. no dice! then i noticed the bios was older so i updated it to the latest version from my usb. still nothing! i re-seated the ssd 100 times. still not being detected. any suggestions? i am strrreessssed

Thanks in advance!

Maybe this will help…not sure but worth a look.
