(Redirected) Boot problems

Hello.

I have the amazing 5547 dell laptop and I recently had it repaired without the Hard drive.

I got it back today, however after trying to install a new SSD, there was no drive at all.

I tried putting my old drive back, but there is no drive at all. All I get is 'No boot device, no media detected check cable' and something about the PCI controller.  I checked the cable, it seems fine.

The BIOS version is A10, I also tried to change between UEFI and Legacy but nothing happens.

I'm so frustrated and sad.

If anyone has any idea what to do, please please feel free to send.
