So recently just changed my psu and got my system to post and everything but for some reason none of my drives are bootable including my ssd which is my boot drive. Interestingly when I plug in a usb it detects it as a bootable drive but not my ssd hdd or m.2. They are showing up in bios but I can’t boot to them. I changed out my sata power and data to be sure it wasn’t faulty cables or something but that didnt seem to work as well.
