1. Safe mode

The system only uses some basic files and drivers to start. Entering safe mode is an important step in diagnosing a problem. If the problem cannot be determined after starting in safe mode, or if safe mode cannot be started at all, then you may need to use the emergency repair disk ERD function to repair the system.

2. Safe Mode with Networking

Start Windows in Safe Mode, including network drivers and services needed to access the Internet or other computers on the network.

3. Safe mode with command prompt

Use the command prompt window to start Windows in safe mode instead of starting through the normal Windows interface. This option is suitable for IT professionals and administrators.

4. Enable startup log

Create the file ntbtlog.txt, which lists all drivers that are installed during startup and may be useful for advanced troubleshooting.

5. Enable VAG mode

Start Windows with the current video driver and low resolution and refresh rate settings. You can use this mode to reset the display settings. Start Windows with the basic VGA driver. This mode is useful when a new graphics card driver is installed that prevents Windows from starting properly, or when the refresh rate is incorrectly set to cause a failure. When starting Windows in Safe Mode, only the most basic graphics driver is used.

6. Last known good configuration (advanced)

Start Windows using the last correctly working registry and driver configuration.

7. Directory Service Restore Mode

Start the Windows domain controller running Active Directory so that the directory service can be restored. This option is suitable for IT professionals and administrators.

8. Debug Mode

Start Windows in advanced troubleshooting mode for IT professionals and system administrators.

9. Disable automatic restart when system fails

Prevent Windows from automatically restarting when Windows fails due to errors. Select this option only if Windows is stuck in a loop (i.e. Windows fails, tries to restart and then fails again).

Extended information:

VGA (Video Graphics Array) is a computer display standard using analog signals proposed by IBM in 1987. This standard has been very important to today's personal computer market. Obsolete. Even so, VGA is still a low standard supported by the most manufacturers. Personal computers must support the VGA standard before loading their own unique drivers.

At present, most computers and external display devices are connected through an analog VGA interface. The display image information generated digitally inside the computer is converted into R and G by the digital/analog converter in the graphics card. , B three primary color signals and horizontal and field synchronization signals. The signals are transmitted to the display device through cables. For analog display devices, such as analog CRT monitors, the signal is directly sent to the corresponding processing circuit to drive and control the picture tube to generate images. For digital display devices such as LCD and DLP, the display device needs to be equipped with a corresponding A/D (analog/digital) converter to convert analog signals into digital signals. After two conversions of D/A and A/D, some image details are inevitably lost. It is understandable that the VGA interface should be used in CRT monitors, but if it is used to connect display devices such as LCDs, the image loss during the conversion process will slightly reduce the display effect.

Mainly used when the display resolution is set too high and the monitor screen is black and cannot display properly. To fix this problem, you must boot into VGA mode, so the resolution and refresh rate will be very low, making it easier for users to change to appropriate settings.
