Question ssd detected by windows installer and not bios

[pogger0009]

I have a gigabyte G1 sniper B6. I tried installing a new M.2 SSD however it doesn't appear in the bios boot menu even though I have already installed windows on it as the windows installer was able to detect it.

You did an installation and the Windows boot went to another hard drive, so nothing appears.
