Help! Laptop won't start. Boot device not found! When I run the hard drive scan it comes back as no hard drive installed. Please check that the power and Data cables are connected properly. It's a laptop. Memory test was good. Wasn't making any noise

Thank you for posting on the HP Support Community.

I see that your HP Pavilion Laptop boots up with startup error " no boot device found" and the computer fails to boot up. I appreciate your efforts to try and isolate the issue. As you've performed relevant troubleshooting steps and the issue persists, this sounds like hardware related issue, Hence, I would request you to contact our Phone Support and our Support Engineers should be able to sort this out for you.
