Issues post upgrading to elcapitan final version
After choosing Internet recovery it shows mountain lion as it was originally installed OS X but it doesn't install as system says newer OS X is installed. Normal recovery method gets stuff at downloading additional components screen and remaining time increases from 5 mins to 30hours and seems stuck that too on 6mb broadband connection.
All this happened after installing El Capitan and computer getting stuck on boot screen after first restart
