Time Machine "The backup volume could not be found" and "Time Machine could not be configured The built-in network interface could not be found".

Time Machine sais:
The backup volume could not be found
and
Time Machine could not be configured
The built-in network interface could not be found

This worked for my hackintosh, I hope it works for you as well!
