M.2 NVME SSD showing up in BIOS but not Windows.

[FlyingNutcase]

I just rebuilt my computer. I have a 256gb m.2 nvme ssd. What had happened is that after everything was built and I got Windows reactivated in my original hard drive. The ssd showed up and I had it initialized. However after I installed proper drivers and flashed to newest bios the ssd stopped showing up.When I enter my computers Bios it shows up there but in windows its not appearing. I checked disk management, I had checked device manager and it isn't anywhere to be found there. The ssd in question is a: Toshiba 256GB m.2 nvme (KXG50ZNV256G).I am currently not planning on using this particular ssd for running my OS, I just wanted to use it for extra storage for my games and such for now till I buy a larger capacity one.

Any help would be greatly appreciated. Thank you in advance!
