Question: No startup disk found
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!
MacBook Pro, macOS High Sierra (10.13.3)
