Question [New Build] Bios not recognizing my NVMe M.2 SSD after installing windows on it in initial setup ?

Jul 11, 2021
Motherboard: Gigabyte GA-z97x-UD5H
Windows 10 Home
Samsung 970 EVO Plus M.2 NVMe SSD (1TB)

I put my new build together, plugged in my windows usb key with windows 10 on it and turned on the computer. Everything seemed to be going fine as it booted from the USB and took me through the installation process. Windows recognized the 1TB SSD as a location to copy the files to, so I selected that. The installation progressed and my computer automatically restarted at the end.

However, after restart, the PC tried to take me back through the installation again. I thought it might be because the USB drive was still connected, but when I disconnect the USB and restart, it gives me an error that there is no bootable device detected ?

The bios doesn't seem to be detecting the SSD, even though windows setup detected it no problem. Any advice?
