No startup disk found

Hello,

Recently my partner's MacBook Pro 13"(mid 2012) froze and after forcing the reboot, it displayed the circle with line through, the Apple logo and then the folder with question mark. After doing some research on what could be the problem and possible solutions, I am clueless.

What I have tried:

Zapped the PRAM/NVRAM
Reset SMC
Tried to boot in safe mode (does not work)
Hardware diagnostic (both regular and extended tests came out OK)
Tried to boot in Recovery mode and verify/repair disk
- Initially there was an error, which I could repair and it would pop up again.
- Now all the drives are OK.
Tried to reinstall OS X but the same issue persists
Tried to wipe the entire HDD and reinstall OS X, same issue
Tried to install an older version (Lion) that the MBP came with, same issue

In the past I have had issues where the SATA cable was slightly broken, causing the HDD to not be detected. This was however a clear Hardware issue as the HDD never showed up. In this case, the HDD shows up in Disk Utility and I can even access it through the Terminal.

I am unable to select this disk as the startup disk.

Any help would be appreciated!

Thank you.

MacBook Pro, macOS High Sierra (10.13.3)

Either the disk has died or must be reformatted. For the former, you need to replace the drive. For the latter, see the following:

Internet/Network Recovery of El Capitan or Later on a Clean Disk

Restart the computer. Immediately after the chime hold down the (Command-Option-R) keys until a globe appears.
The Utility Menu will appear in from 5-20 minutes. Be patient.
Select Disk Utility and click on the Continue button.
When Disk Utility loads select the drive (usually, the out-dented entry) from the side list.
Click on the Erase tab in Disk Utility's main window. A panel will drop down.
Set the partition scheme to GUID.
Set the Format type to APFS (SSDs only) or Mac OS Extended (Journaled.)
Click on the Apply button, then click on the Done button when it activates.
Quit Disk Utility and return to the Utility Menu.
Select Reinstall OS X and click on the Continue button.

Note:

1. To install the version of OS X that was currently installed use Command-Option-R.

2. To install the original factory version when the computer was new use Command-Option-Shift-R.
