Help! Newly built system, cant boot

[RJ56Hours]

I just built a system of 9700k, 2070. It's a asus motherboard, but it kept booting into the bios instead of my windows storage. When everything in bios was in default, the cpu fan missing thing kept showing up, so I went to ignore cpu fan speed in bios(pic). After that, it just kept booting into bios. I enabled CMS, but nothing. I put a usb boot drive into the computer, then i can see boot options (pic). But my sdd and hdd is no where to be found. So if I remove the usb, i cant even find Boot Option. Anyone familiar with the situation?

It was an sdd(windows in it) which I was using in an other computer and it's newly bought so it worked fine. I am also using a water cooler so I had that cpu fan thingy

Well re-installing windows would work, but are the drives detected in the bios, not in the boot menu, but sata menu?

If the windows install existed in another PC, the motherboard might reject it to avoid a driver conflict.

Where's the sata menu thingy

So my best bet would  be sticking the usb loaded with windows, then reinstall the damn thing?

Drivers could be interfering with your new motherboard/cpu , so yeah, it's suggested to reinstall OS freshly.
