Windows crashed / second nvme drive not seen ?

Hello,

So my system crashed last night, received a warning that onedrive was corrupt and to reinstall, and then the system hung. reboot and says profiles services not loading, unable to log in. Reinstalled system at that point from msi recovery software, actually tried to do the relocate users to second drive tutorial and noticed my second drive was not seen by windows, upon investigation was not seen in Bios. Installed this second drive 2 months back. Originally was not seen in bios on installation, but had a firmware update (for battery management) and drive was seen after that. Any Ideas on what I can do ?

windows 10 home version 1909

thanks
