boot device not found

[sboyd]

On start up i am getting BOOT DEVICE NOT FOUND. I removed the hard drive and reinstalled it and got the same thing. I then put the hard drive into a different computer and it works fine. I reset the BIOS to default did all the tests and everything passes.

I also installed a known good hard drive and still got the same message

@sboyd, It was a quick response, I was indeed waiting for your response.

I appreciate your efforts for trying out the steps.

As I recommended you to run system diagnostics on your PC, Did you try running the system diagnostics on your PC, Can you please share the results.
