Thanks soljah but I think you missed the point.
The error is not normal in the sense it's a necessary part of the install process, however error 2011 means the cIOS hasn't installed properly.
This is a very common issue and loads of people have had the problem.
There's a solution of course. Your cIOS is not accepting the install so let's change it so it will.
Patch your cIOS the easy way
