[Help] “The system cannot find any bootable devices.”

Specs: 8700 Asus h370 itx Gskill aegis 2*8 3000 Samsung eco 840 250gb “” 500gb Corsair sf600 MSi 1060

Issue: I just finished the build and can’t get it to boot to windows. It’s reading everything just fine in the bios, but it’s not “finding any bootable devices.” The windows is on an ssd and has been through two completely different builds with no issues until now. I’m at a loss on what to do.

Update: ssd still boots just fine as the independent ssd in the previous build. Going to wire in just the 1 ssd in new build and see if we can boot.

Update2: Sole ssd in new build still doesn’t work. Seeing but not recognizing as bootable drive. Changed sata ports and still nothing/:

Update3: Launched in CSM in boot menu. Got through to windows. Thought I had already tried that 😒
