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 (see 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
(see configfile) for this.
