One menu only
Note: If you have no user payload files or .mnu files present and you use the MainMenu Only configuration file and use set DEFMENU=0, then because the menu will be empty, E2B will just boot to the grub4dos prompt. Please ensure that at least one payload file is present in the \_ISO\MAINMENU folder.
If you want to add Windows Install ISOs to the Main menu, please see this page.
