if you update the bios, it will reset all the settings. what settings did you change when you install the m.2 the first time?

There are 2 probable reasons for the problem.

1. BIOS is configured for UEFI boot only, but windows is installed in legacy mode.
2. BIOS is configured for legacy boot only, but windows is installed in UEFI mode.

First option is more likely. Change BIOS settings to match windows install mode.
