ok so i wanted to do a clean install on my prebuilt desktop. made a Windows USB stick, booted it, clicked through to teh disk selection srceen and got this:

Reboot and Select proper Boot device
or Insert Boot Media in selected Boot device and press a key
No bootable device -- insert boot disk and press any key
no drives at all, the BIOS clearly shows teh NVMe SSD with its correct model and size... ive remade teh USB stick twice. someone mentioned I might need ASRock A770DE Bios 1.00 for DOS loaded during setup, but Ive never had to do that before and I have no idea which file to point teh installer at... help me before I return a perfectly good SSD. im about to throw this thing out the window lol
