Interfaces Load Order

When GRUB loads its second stage boot loader, it first searches for its
configuration file. Once found, the menu interface bypass screen is displayed. If
a key is pressed within three seconds, GRUB builds a menu list and displays the
menu interface. If no key is pressed, the default kernel entry in the GRUB menu
is used.

If the configuration file cannot be found, or if the configuration file is
unreadable, GRUB loads the command line interface, allowing the user to
type commands to complete the boot process.
If the configuration file is not valid, GRUB prints out the error and asks
for input. This helps the user see precisely where the problem occurred.
Pressing any key reloads the menu interface, where it is then possible to
edit the menu option and correct the problem based on the error reported
by GRUB. If the correction fails, GRUB reports an error and reloads the
menu interface.
