Hi llkin turk. Hope you are trying to prevent closing until the user actually wish to close. for that you can handle the closing event
using the following code snippet.   void Form2_FormClosing(object sender, FormClosingEventArgs e)
{
if(!(form1 as Form1).checkBox1.Checked)
e.Cancel = true;
}

I don't know why that should be so unless you have code in Form2 which automatically minimizes it when it loses input focus.
But, if you handle its Resize event as follows, it should pop-up again if there's any attempt to minimize it:
private void Form2_Resize(object sender, EventArgs e)         {             if (this.WindowState == FormWindowState.Minimized)             {                 this.WindowState = FormWindowState.Normal;             }         }

Answer

Hello,
But,usually when user clicks on first form second form minimize.

I may be missing something here but, as long as you've opened the second form using Show() rather than ShowDialog(), then the user will be able to move the input focus back to the main form without the need to close the second form first.
