9.7.2. Directives des fichiers de configuration

chainloader </path/to/file> — Loads the specified file as a chain loader. Replace </path/to/file> with the absolute path to the chain loader. If the file is located on the first sector of the specified partition, use the blocklist notation, +1.

color <normal-color> <selected-color> — Allows specific colors to be used in the menu, where two colors are configured as the foreground and background. Use simple color names such as red/black. For example:

color red/black green/blue

default=<integer> — Replace <integer> with the default entry title number to be loaded if the menu interface times out.

fallback=<integer> — Replace <integer> with the entry title number to try if the first attempt fails.

hiddenmenu — Empêche l'affichage de l'interface menu de GRUB, chargeant l'entrée par défaut (default) lorsque la durée d'attente initiale (timeout) est dépassée. L'utilisateur peut visualiser le menu standard de GRUB en appuyant sur la touche Échap.

initrd </path/to/initrd> — Enables users to specify an initial RAM disk to use when booting. Replace </path/to/initrd> with the absolute path to the initial RAM disk.

kernel </path/to/kernel> <option-1> <option-N> — Specifies the kernel file to load when booting the operating system. Replace </path/to/kernel> with an absolute path from the partition specified by the root directive. Multiple options can be passed to the kernel when it is loaded.

password=<password> — Prevents a user who does not know the password from editing the entries for this menu option.

Optionally, it is possible to specify an alternate menu configuration file after the password=<password> directive. In this case, GRUB restarts the second stage boot loader and uses the specified alternate configuration file to build the menu. If an alternate menu configuration file is left out of the command, a user who knows the password is allowed to edit the current configuration file.

root (<device-type><device-number>,<partition>) — Configures the root partition for GRUB, such as (hd0,0), and mounts the partition.

rootnoverify (<device-type><device-number>,<partition>) — Configures the root partition for GRUB, just like the root command, but does not mount the partition.

timeout=<integer> — Specifies the interval, in seconds, that GRUB waits before loading the entry designated in the default command.

splashimage=<path-to-image> — Specifies the location of the splash screen image to be used when GRUB boots.

title group-title — Définit le titre à utiliser avec un groupe donné de commandes utilisé pour charger un système d'exploitation ou un noyau.
