Boot Order refers to the sequence in which a computer’s firmware searches for and loads operating systems or other bootable devices during the startup process. In Ubuntu 22.04, the boot order is typically set to prioritize the operating system installed on the computer’s internal hard drive or solid-state drive. However, users can modify the boot order to boot from other devices, such as a USB drive or network.

Customizing the boot order can be useful in various scenarios. For instance, it allows users to boot from a live USB drive to install or troubleshoot the operating system. Additionally, it enables them to select a different operating system if multiple ones are installed on the computer. Modifying the boot order also helps in resolving boot-related issues, such as when the computer fails to boot from the primary drive due to hardware problems or software corruption.

To modify the boot order in Ubuntu 22.04, users can access the Firmware Settings menu during the computer’s startup process. The specific key to press for this menu may vary depending on the computer’s manufacturer, but it’s typically one of the function keys (F1, F2, F10, or F12). Once in the Firmware Settings menu, users can navigate to the Boot Options section and adjust the boot order using the provided options.
