grub: normal

 
 16.3.52 normal
 --------------
 
  -- Command: normal [file]
      Enter normal mode and display the GRUB menu.
 
      In normal mode, commands, filesystem modules, and cryptography
      modules are automatically loaded, and the full GRUB script parser
      is available.  Other modules may be explicitly loaded using
      'insmod' (⇒insmod).
 
      If a FILE is given, then commands will be read from that file.
      Otherwise, they will be read from '$prefix/grub.cfg' if it exists.
 
      'normal' may be called from within normal mode, creating a nested
      environment.  It is more usual to use 'configfile' (⇒
      configfile) for this.
