# Systemd Boot
systemd-boot is a simple UEFI boot manager which executes configured EFI images. The default entry is selected by a configured pattern (glob) or an on-screen menu to be navigated via arrow keys. It is included with [systemd](systemd/Systemd.md), which is installed on an Arch system by default.

It is simple to configure but can only start EFI executables such as the [Linux](Linux.md) kernel EFISTUB, UEFI shell, GRUB, or the [Windows](../../windows/Windows.md) Boot Manager.

## Install
Install:
```shell
bootctl install
```

Update:
```shell
bootctl update
```

## Configuration
The loader configuration is stored in the file `_esp_/loader/loader.conf`
Example:
```
default  arch.conf
timeout  4
console-mode max
editor   no
```

### Adding loaders
_systemd-boot_ will search for boot menu items in `_esp_/loader/entries/*.conf`

Values:
- `title` : Name
- `version` : Kernel Version
- `efi` : EFI Executable
- `options` : Kernel Parameter

Example:
`_esp_/loader/entries/arch.conf`
```
title   Arch Linux
linux   /vmlinuz-linux
initrd  /intel-ucode.img
initrd  /initramfs-linux.img
options root="LABEL=_arch_os_" rw
```

## Changing Boot
Choosing next boot:
```shell
systemctl reboot --boot-loader-entry=arch-custom.conf
```

Firmware Setup:
```shell
systemctl reboot --firmware-setup
```
