Using the entropy function formalism we compute the entropy of supersymmetric as well as non-supersymmetric black holes in N = 2 Supergravity in 4 dimensions with higher derivative correction. For supersymmetric case we see that there is an exact matching with earlier results derived using a 5 dimensional description of the same system whereas for non-supersymmetric case the results does'nt match and we provide possible explanation for the discrepancy.
