bootctl(1)



NAME

   bootctl - Control the firmware and boot manager settings

SYNOPSIS

   bootctl [OPTIONS...] status

   bootctl [OPTIONS...] update

   bootctl [OPTIONS...] install

   bootctl [OPTIONS...] remove

DESCRIPTION

   bootctl checks, updates, installs or removes the boot loader from the
   current system.

   bootctl status checks and prints the currently installed versions of
   the boot loader binaries and all current EFI boot variables.

   bootctl update updates all installed versions of systemd-boot, if the
   current version is newer than the version installed in the EFI system
   partition. This also includes the EFI default/fallback loader at
   /EFI/BOOT/BOOT*.EFI. A systemd-boot entry in the EFI boot variables is
   created if there is no current entry. The created entry will be added
   to the end of the boot order list.

   bootctl install installs systemd-boot into the EFI system partition. A
   copy of systemd-boot will be stored as the EFI default/fallback loader
   at /EFI/BOOT/BOOT*.EFI. A systemd-boot entry in the EFI boot variables
   is created and added to the top of the boot order list.

   bootctl remove removes all installed versions of systemd-boot from the
   EFI system partition, and removes systemd-boot from the EFI boot
   variables.

   If no command is passed, status is implied.

OPTIONS

   The following options are understood:

   -h, --help
       Print a short help text and exit.

   --version
       Print a short version string and exit.

   --path=
       Path to the EFI System Partition (ESP). If not specified, /efi,
       /boot, and /boot/efi are checked in turn. It is recommended to
       mount the ESP to /boot, if possible.

   --no-variables
       Do not touch the EFI boot variables.

EXIT STATUS

   On success, 0 is returned, a non-zero failure code otherwise.
