WinXP: System 8 startup mode details

Press F8 when the system starts Windows XP, the screen will display the advanced options menu of Windows XP startup, through these options you can choose different modes to start Windows XP. The meaning of these options is introduced below.

1. Safe Mode: When you start Windows XP in Safe Mode, the system only calls some of the most basic files and drivers, only uses a small number of devices, and does not load any content in the startup group; it cannot be connected to the network after startup, and many devices cannot Normal use (BR drive can be used in Windows XP safe mode). This mode is useful for diagnosing problems that arise from the system. If a newly added device or a problem with the driver changes the system, you can enter safe mode, remove the device in question, and then install it. If the problem cannot be solved in Safe Mode, you will most likely need to re-install the installation CD to repair the system.

2. Safe mode with network connection: This mode uses basic files and drivers. Compared with "safe mode", it also loads network drivers. Its main function is basically the same as security mode, but it does not support PCMCIA cards. (A removable card that follows the specifications of the Personal Computer Memory Card International Association) networking. If the computer is connected to the network and no errors are detected when booting in secure mode, it may be a network card error. Use this mode to find some hidden problems in safe mode.

3. Safe mode at the command line prompt: Start Windows with basic files and drivers, and enter the command prompt window after booting. Note that the desktop and start menu will not appear in this mode. If you accidentally close the DOS
window, you can only turn off the "Windows Task Manager" by pressing "Ctrl+Alt+DEL". Then select it from its "Shutdown" menu; or load a new task explorer in the Task Manager. Exe can appear on the desktop and start menu, and then can be shut down like normal mode.

4. Enable boot log: Boot Windows and record the system to load normally and the program that is not loaded normally (the file name is ntbtlog.txt, located in the Windows XP installation directory winnt), through this log file can be analyzed when the system starts up The root cause of the problem.

5. Enable VGA mode: Use standard VGA driver to boot Windows. If Windows causes an error after installing a new display driver, you can enter this mode, then remove the wrong driver and install other drivers. This mode is often used to solve the problem of system startup abnormality caused by graphics card driver error.

In fact, standard VGA drivers are used in "Safe Mode", "Network Security Mode", and "Command Prompt Security Mode".

6. Last correct configuration: After a problem occurs in the system (such as the newly added driver and hardware may be inconsistent, the system may not start properly),

Using "Last Known Good Configuration" to start Windows can generally solve these problems. problem. Of course, if there is a system problem due to system file loss or corruption, it can't be solved (in this case, you can go to the system configuration utility and click "Expand File" to extract the corresponding file to recover).

7. Directory Service Recovery Mode: This mode is used to restore the Sysvol directory and Active Directory (Active Directory) services on domain controllers.

It is actually a kind of security mode.

8. Debug mode: If some hardware uses real-mode drivers (such as some drivers loaded in config.sys and autoexec.bat) and causes the system to fail to boot properly, you can use debug mode to check for real-mode driver generation. Conflict. In this mode, the system repeatedly tests and determines whether to use or cancel the drivers in config.sys or autoexec.bat to discover device drivers that cause system configuration problems.
