SSD no longer recognised in disk utility/bios

So I managed to successfully install 10.12.6 at first but I had a problem after a few days. Gigabyte support told me to flash BIOS which made it even worse while the problem was only incompatible HWmonitor gpu sensor. Anyway I formatted my Toshiba rd400 ssd (attached via m.2 slot on mobo) and re-flashed my BIOS back to the original version (F3) but the ssd won't show up in my BIOS.

I also tried to install via Hackintosh Zone but it also is not finding my ssd (disconnected all other hard disks). Can someone please help me out?

Specs:

-Gigabyte G170X Ultra Gaming

-i7 6700k 4.0Ghz

-Gigabyte GTX 1070

-Toshiba rd400 ssd
