I have also tried: (a) specifying the startup disk (problem still persists) (b) attempting to start in safe mode (problem persists) doing the NVRAM reset (problem persists). I’m still able to boot into recovery mode (CTRL-R at Startup), however running disk repair on my MacBook HD does NOT solve the problem. Rebooting still produces a prohibitory symbol.
