When you score the final kill on the E-1 Boss, the map gauge during the battle explodes, indicating that the boss is no longer an issue and you can move on to E-2. If that map gauge didn't explode and still shows up on the map, then you didn't finish off the flagship of the enemy fleet. You need to kill the first ship in the boss fleet.
