Re: Has anyone found a solution to the "unable to find a bootable option" error on the lumia 822??
Its such a rare occurrence and we don't have much leeway under the hood of Windows Phone for such a fix, I'm afraid sending it to Verizon or Nokia for service is the only way.
However, I don't have experience with such an issue. Potentially (sheer conjecture) you could try reflashing it using Nokia Care Suite (I think that's the name). I would probably try that first, making sure its the 822 ROM being loaded.
