Initial Default
* GRUB 2 will boot straight into the default operating system if no other
operating system is detected. No menu will be displayed. If another operating
system is detected, the GRUB 2 menu will display.
Timed Display
*
The menu is displayed for a predetermined number of seconds. The default
entry is highlighted and other selections may be made by the user until the
timeout expires. The default timeout is now 3 seconds. The timer continues
until any key is pressed or the highlighted entry is selected by pressing
ENTER. If no user input is made GRUB 2 boots the default entry at the end of
the timeout period.
* Once a key has been pressed the timeout is deactivated and the user must
make a selection manually.
*
The default entry is determined by the DEFAULT= setting in
/etc/default/grub; the first "menuentry" has a value of "0".
Hidden
* No menu entries are displayed. The splash screen, if configured, will be
displayed.
* The user can interrupt the boot process and display the menu by holding
down the SHIFT key until the menu displays.
o GRUB 2 searches for a depressed SHIFT key signal during boot. If
the key is pressed or GRUB 2 cannot determine the status of the key, the menu
is displayed.
*
The time the screen remains blank but available for display is
determined by a setting in /etc/default/grub.
*
GRUB 2 can display a countdown timer to provide visual feedback on the
time remaining until the default selection is chosen. The timeout setting is
enabled in /etc/default/grub
*
At the end of the timeout, the default entry determined by settings in
/etc/default/grub will be selected.
I'll definitely keep digging on this. While holding the shift key during
boot can be done, it's not the kind of work I like seeing stuff go out the door
with.
