Here is a code which all you need is to copy and paste it in c# file amd you will have a menu then attach this script to the Main Camera in the scene and you can pick if you want a background image to add to it:

using UnityEngine;
using System.Collections;

public class Menu : MonoBehaviour 
{
    public GUISkin guiSkin;
    public Texture2D background, LOGO;
    public bool DragWindow = false;
    public string levelToLoadWhenClickedPlay = "";
    public string[] AboutTextLines = new string[0];


    private string clicked = "", MessageDisplayOnAbout = "About

";
private Rect WindowRect = new Rect((Screen.width / 2) - 100, Screen.height / 2, 200, 200);
private float volume = 1.0f;

    private void Start()
    {
        for (int x = 0; x < AboutTextLines.Length;x++ )
        {
            MessageDisplayOnAbout += AboutTextLines[x] + "

";
}
MessageDisplayOnAbout += “Press Esc To Go Back”;
}

    private void OnGUI()
    {
        if (background != null)
            GUI.DrawTexture(new Rect(0,0,Screen.width , Screen.height),background);
        if (LOGO != null && clicked != "about")
            GUI.DrawTexture(new Rect((Screen.width / 2) - 100, 30, 200, 200), LOGO);

        GUI.skin = guiSkin;
        if (clicked == "")
        {
            WindowRect = GUI.Window(0, WindowRect, menuFunc, "Main Menu");
        }
        else if (clicked == "options")
        {
            WindowRect = GUI.Window(1, WindowRect, optionsFunc, "Options");
        }
        else if (clicked == "about")
        {
            GUI.Box(new Rect (0,0,Screen.width,Screen.height), MessageDisplayOnAbout);
        }else if (clicked == "resolution")
        {
            GUILayout.BeginVertical();
            for (int x = 0; x < Screen.resolutions.Length;x++ )
            {
                if (GUILayout.Button(Screen.resolutions[x].width + "X" + Screen.resolutions[x].height))
                {
                    Screen.SetResolution(Screen.resolutions[x].width,Screen.resolutions[x].height,true);
                }
            }
            GUILayout.EndVertical();
            GUILayout.BeginHorizontal();
            if (GUILayout.Button("Back"))
            {
                clicked = "options";
            }
            GUILayout.EndHorizontal();
        }
    }

    private void optionsFunc(int id)
    {
        if (GUILayout.Button("Resolution"))
        {
            clicked = "resolution";
        }
        GUILayout.Box("Volume");
        volume = GUILayout.HorizontalSlider(volume ,0.0f,1.0f);
        AudioListener.volume = volume;
        if (GUILayout.Button("Back"))
        {
            clicked = "";
        }
        if (DragWindow)
            GUI.DragWindow(new Rect (0,0,Screen.width,Screen.height));
    }

    private void menuFunc(int id)
    {
        //buttons 
        if (GUILayout.Button("Play Game"))
        {
            //play game is clicked
            Application.LoadLevel(levelToLoadWhenClickedPlay);
        }
        if (GUILayout.Button("Options"))
        {
            clicked = "options";
        }
        if (GUILayout.Button("About"))
        {
            clicked = "about";
        }
        if (GUILayout.Button("Quit Game"))
        {
            Application.Quit();
        }
        if (DragWindow)
            GUI.DragWindow(new Rect(0, 0, Screen.width, Screen.height));
    }

    private void Update()
    {
        if (clicked == "about" && Input.GetKey (KeyCode.Escape))
            clicked = "";
    }
}
