Windows XP Boot Process

Last Updated on Mon, 02 Jan 2023 | Operating Systems

To begin the boot process, you first turn on the computer, which is called a cold boot. The computer performs the power-on self test (POST). Because the video adapter has not yet been initialized, any errors that occur at this point in the boot process will be reported by a series of audible tones, called beep codes.

After the POST, the BIOS locates and reads the configuration settings that are stored in the CMOS. This configuration setting is the order in which devices will be tried to see whether an operating system is located there. The BIOS boots the computer using the first drive that contains an operating system.

When the drive with the operating system is located, the BIOS locates the Master Boot Record (MBR). The MBR locates the operating system boot loader. For Windows XP, the boot loader is called NT Loader (NTLDR).

    What is booting process?

    • Booting is the process of starting a computer operating system after it has been turned on. During the booting process, the computer runs through a series of diagnostic tests to check the hardware and software components of the system. Once passed, the operating system is loaded, and then the remaining configuration settings and processes necessary for the computer to function properly are initialized.
