What is the meaning of the Windows XP boot menu?

What is the meaning of the Windows XP boot menu: I recently installed the Windows XP operating system, I know that when I press F8 at startup or when the computer does not start properly, Enter the advanced options menu of Windows XP startup, where you can choose to start Windows XP in 8 different modes except normal startup. What do these modes mean?

(1) Safe Mode: When you start Windows XP in Safe Mode, the system starts with only some of the most basic files and drivers. Entering safe mode is an important step in diagnosing a fault. If the problem cannot be determined after the security mode is started, or if the security mode cannot be started at all, then you may need to use the emergency repair disk ERD function to repair the system.

(2) Network security mode: Similar to security mode, but added support for network connection. This option is useful for troubleshooting Windows XP boot failures in a LAN environment.

(3) Security mode of the command prompt: similar to the security mode, only use the basic files and drivers to start Windows XP. But after login, the command prompt appears instead of the Windows desktop.

(4) Enable boot log: Start Windows XP and log all drivers and services loaded by the system to a file. The file name is ntbtlog.txt and is located in the Windir directory. This log is useful for determining the exact cause of a system startup problem.

(5) Enable VGA mode: Start Windows XP with basic VGA driver. This mode is installed when a new graphics driver that prevents Windows XP from starting properly is installed, or if the refresh frequency is set incorrectly. Very useful. When starting Windows XP in Safe Mode, only the most basic graphics driver is used.

(6) The last time the correct configuration: Select "Start Windows XP with 'Last Known Good Configuration" is a way to solve problems such as newly added drivers and hardware do not match. Starting in this way, Windows XP only restores the information under the registry key HklmSystemCurrentControlSet. Any changes made in other registry keys remain the same.

(7) Directory Service Recovery Mode: Not applicable to Windows XP Professional. This is for the Windows XP Server operating system and is only used to restore the Sysvol directory and Active Directory directory service on the domain controller.

(8) Debug mode: Start Windows XP and send debugging information to other computers via serial cable. If you are installing or have installed Windows XP on your computer using the Remote Installation Service, you can see additional options related to using the Remote Installation Services to recover your system.
