Bootmenü

The boot menu, also known as the bootloader or startup menu, is a user interface that appears when a computer is powered on or restarted. Its primary function is to allow the user to select the operating system or boot device to load. The boot menu is typically accessed by pressing a specific key combination during the initial stages of the boot process, such as F8, F12, or Esc, depending on the computer's manufacturer and BIOS/UEFI settings.

The boot menu displays a list of available operating systems, boot devices, and sometimes diagnostic tools. Users can navigate this list using the keyboard and select the desired option to boot into. This feature is particularly useful for dual-boot systems, where multiple operating systems are installed on the same computer, allowing users to choose which one to load each time they start their machine.

In addition to selecting the operating system, the boot menu may also provide options for entering the BIOS/UEFI setup, booting from a USB drive or CD/DVD, or accessing recovery tools. These options can be helpful for troubleshooting hardware issues, repairing the operating system, or installing new software.

The boot menu is a crucial component of the computer's startup process, enabling users to control which operating system or boot device is loaded, and providing access to essential diagnostic and recovery tools. Its functionality and appearance can vary depending on the computer's manufacturer, BIOS/UEFI version, and installed operating systems.
