M.2 SSD showing up in bios not windows

[Xx_osos_xX]

I bought a 240gb WD Green M.2 SSD and it shows up in the bios but not in windows :(

i was dum enough to throw away the packaging so i can't return it now. i want to use it :(

when i go to initialize it in disk management it simply doesn't show up :(

i tried Windows Memory Diagnostic and it didn't work :(

my pc:

i5 4460

MSI Gaming 3 h97

2x8gb ddr3

AMD RX 5700xt

730 watt thermaltake
