How to Change Boot Order in Ubuntu

The order in which a computer looks for nonvolatile data storage devices with program code to load the operating system is known as the boot sequence (OS). ROM is used to initiate the boot procedure on a Macintosh, while BIOS is used on Windows. The CPU takes charge and loads the operating system into system memory once the instructions are found.

Hard disc drives, floppy drives, optical drives, flash drives, and other devices are frequently provided as boot order alternatives in BIOS settings. Using the CMOS setup, the user can customize the boot sequence. Boot order or BIOS boot order are other names for boot sequence.

In dual boot mode, we frequently need to install two distinct operating systems side by side on our workstation. Regardless of our intentions, when we intend to install a second operating system, such as Ubuntu, it immediately appears as the primary operating system. We have no plans for it to become the default operating system. We intend to use it as a backup operating system. In such cases, we must adjust the boot order according to our preferences, and this article will show you how to do so in Linux.
