Rotate bullet on 90 degrees

Unity Engine
1

I have code on fire :

void onFire()
{
    Vector3 SpawnPoint = flare.transform.position;
    Quaternion SpawnRoot = flare.transform.rotation;
    GameObject Bullet = Instantiate (bulletPrefab, SpawnPoint, SpawnRoot) as GameObject;
    Rigidbody Run = Bullet.GetComponent<Rigidbody>();
    Run.AddForce(Bullet.transform.forward * 2*Time.deltaTime, ForceMode.Impulse);
}

But bullet always position
IIIIIII
IIIIIII <---------- vertical
IIIIIII
IIIIIII
And I need it must apeared in horizontal

How Can I do this?

ok , I got it after that codehave to add one more line:

Bullet.transform.eulerAngles = new Vector3(-90, Bullet.transform.eulerAngles.y, Bullet.transform.eulerAngles.z);
