First - Ensure BIOS boot menu on correct choices so that OS can see all drives either NVME or AHCI
Add New Entry tab
- Locate the inaccessible OS on NVME drive i.e. C:\
Edit Boot Menu tab
- Hit Save Settings button

Is it seated properly? This happens on my laptop (Dell 7490 and a Kingstong NV1) but if I twist the entire laptop a bit it's fine (known problem for the model).

1) Double check if boot keys aren't enabled (do you know if Secure Boot was enabled along side TPM module ?).
2) Make sure you are booting of Windows Boot Manager (not actual NVMe), with CSM with EFI on boot devices option enabled (or plain no CSM).
3) If your system used Boot Secure keys, and they were reset (+ you didn't make a backup copy of them) - regardless of cause, you are truly screwed.
