käynnistysvalikossa

Käynnistysvalikko refers to the boot menu or startup menu in a computer system. It is a special interface that appears briefly after the computer is powered on and before the operating system begins to load. The purpose of the käynnistysvalikko is to provide the user with options that can alter the boot process.

Common options found in a käynnistysvalikko include the ability to select which storage device the computer should boot from, such as a hard drive, SSD, USB drive, or optical drive. This is useful for installing a new operating system, running diagnostic tools, or booting into a recovery environment. It can also allow users to choose between different operating systems installed on the same computer, a process known as dual-booting or multi-booting.

Accessing the käynnistysvalikko typically involves pressing a specific key on the keyboard immediately after turning on the computer. The exact key varies depending on the computer's manufacturer and BIOS/UEFI firmware, but common keys include F8, F10, F11, F12, or the Delete key. The system usually displays a message on the screen indicating which key to press to enter setup or access the boot menu.

In some cases, the boot menu might be integrated with the BIOS/UEFI setup utility, requiring the user to navigate through different menus to select the boot order. Modern systems often present a more user-friendly graphical boot menu. Understanding and utilizing the käynnistysvalikko is an essential skill for system administrators and advanced users for troubleshooting and system management.
