Do You want to Show us a Little bit of Your code? We can´t exactly answer if You do not explain a bit more. But starting activity from broadcast Receiver is just simple as starting activity in the usual way:

   Intent intent = new Intent(context.getApplicationContext(), YourActivity.class);
   intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
   context.startActivity(intent);

Use this in Your onReceive()....and don´t Forget to Register Your Receiver to the manifest.

EDIT

So if You want to start an Action 5 minutes after reboot, it should be something like this:

start another boradcastreceiver in Your BootCompleted Receiver:

   AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);

   Intent intent = new Intent(context,SecondBroadcastReceiver.class);
   PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0,
   intent, PendingIntent.FLAG_ONE_SHOT);
   am.set(AlarmManager.RTC_WAKEUP,
   System.currentTimeMillis() + 300000, pendingIntent); //5 minutes are 300000 MS

The BroadcastReceiver:

        public class SecondBroadcastReceiver extends BroadcastReceiver {



       @Override
          public void onReceive(Context context, Intent intent) {

              Intent i= new Intent(context, YourService.class);

              context.startService(i); 

           }
       }

The Service

    public class YourService extends Service {

       @Override
        public int onStartCommand(Intent intent, int flags, int startId) {

       //start here the Action You will do, 5 minutes after reboot

       return Service.START_NOT_STICKY;
   }

      @Override
       public IBinder onBind(Intent intent) {

       return null;
    }
}

But this is only from scratch, I can´t test the code for now, have no IDE here. So I am not sure about givin the context to Intent and PendingIntent in Your BootCompletedReceiver.
