It appears that unibeast failed after trying to install boot loader, as shown in the log below. Doesn't help me solve the problem, though.
In Any case, I have a new problem. After reading the troubleshooting notes, I deleted my copy of ElCapitan install and tried to get another one, but the App store now won't let me get any OSs. What next?
