Game Situation: Batter Hit by Pitch on Bunt Attempt

 
With a runner on first base (R1) and a 1-1 count, the batter squares to bunt. The batter offers at the pitch, misses hitting the pitch, but the pitch hits the batter in the thigh, and the ball rolls fair up the third base line. R1 advances to second base and the batter arrives safely at first base.
 
What does the umpire do now?
 
Call
In the situation below, the batter struck at the pitch, so a strike should be added to the count. Since the pitch hit the batter, the ball is dead. R1 must return to first base and the batter must return to the plate with a 1-2 count.
