   Look in C:\Program Files\Microsoft SQL Server\110\Setup Bootstrap\Log. You   
   should find one directory per installation attempt. The log files are   
   certainly verbose, but you find something helpful there.   
      
   From your description, it appears that your machine was not in best shape   
   when you started.
