Gummiboot is an open source boot loader for computers with UEFI firmware. It allows users to easily install and boot multiple operating systems, including Linux, Windows, and OS X. It is designed to be fast and reliable, and is often used as the primary boot loader on UEFI-based machines. Gummiboot is designed to be user friendly and works with most UEFI-compliant hardware. It is capable of booting multiple operating systems from a single disk or partition, and allows users to choose which operating system to boot from a simple text-based menu. Gummiboot also supports booting from multiple disks or partitions, so users can easily add or remove operating systems as needed.
