systemd-boot – simple UEFI boot manager

systemd-boot, previously called gummiboot (German for “rubber dinghy”), is a simple Unified Extensible Firmware Interface (UEFI) boot manager which executes configured EFI images.

Developed by Red Hat employees, gummiboot was intended to be a minimal alternative to GNU GRUB that “just works”. It automatically detected bootable images (including Linux kernel images, operating systems, and other boot loaders), did not require a configuration file, provided a basic menu-based interface, and could also integrate with systemd to provide performance data.

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.

This is free and open source software.
