hi guys, im currently installing my new pc. I took my old laptop ssd nvme m2 and put it in my new cpu.

now its giving this message:

Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key

I tried to clean my ssd and swap it in the laptop again, but it does not work.

windows is installed and everything

i tried also to change CSM options, but neither of them worked

Setup:

B450m asus

WDGreen nvme m.2
