Ssd detected in BIOS But can’t boot to drive

[Celes]

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.

First, Use a bootable Windows 10 Recovery disk to run "Startup Repair". It will attempt to fix it automatically.

If failed, continue to next step.

 

If you have a UEFI compatible motherboard, select the correct .EFI file associated with the boot drive. Look on your UEFI dashboard for something like "boot options" or "Path for boot". Select this option and it should show a DOS like file browser, use this to navigate to your boot disk and find the path to the .EFI file. Path should be similar to this if you are running Windows 10.

\EFI\BOOT\BOOTX64.EFI

Attempt all other methods of repair before you select the EFI File.
