Question SSD no longer detected in BIOS after installing windows


Feb 3, 2017
Hello everyone,

I’m on mobile so please excuse any spelling mistakes but my computer has seen better days.

I bought two SSD’s with my amazon gift cards from Christmas. My pc originally only had a 500 GB 7200 rpm hdd. I installed both ssd’s properly and fastened them both in. I started my PC, found the MP500 drive from Corsair that I want to install windows on. All was well after the install.

Windows was up and running just fine, it had prompted me to restart for hardware changes. I happily obliged. I restarted and it took me to the BIOS because I forgot to set my ssd as my #1 boot priority. But now, my M.2 drive is nowhere to be found? Troubleshooting steps are listed below.

  • disabled csm, didn’t work
  • disabled csm, enabled secure boot with restored keys, didn’t work
  • enabled csm and set both options to legacy instead of UEFI didn’t work
  • disabled xmp, didn’t work
  • booted into windows install media, tried running diskpart and chkdisk commands to see if it even detects it. Neither did
Anyone have any other suggestions?
