A description of the Safe Mode Boot options in Windows XP

[phoonk]

• Safe Mode (SAFEBOOT_OPTION=Minimal): This option uses a minimal set of device drivers and services to start Windows.
• Safe Mode with Networking (SAFEBOOT_OPTION=Network): This option uses a minimal set of device drivers and services to start Windows together with the drivers that you must have to load networking.
• Safe Mode with Command Prompt (SAFEBOOT_OPTION=Minimal(AlternateShell)): This option is the same as Safe mode, except that Cmd.exe starts instead of Windows Explorer.
• Enable VGA Mode: This option starts Windows in 640 x 480 mode by using the current video driver (not Vga.sys). This mode is useful if the display is configured for a setting that the monitor cannot display.

Note Safe mode and Safe mode with Networking load the Vga.sys driver instead.
• Last Known Good Configuration: This option starts Windows by using the previous good configuration.
• Directory Service Restore Mode: This mode is valid only for Windows-based domain controllers. This mode performs a directory service repair.
• Debugging Mode: This option turns on debug mode in Windows. Debugging information can be sent across a serial cable to another computer that is running a debugger. This mode is configured to use COM2.
• Enable Boot Logging: This option turns on logging when the computer is started with any of the Safe Boot options except Last Known Good Configuration. The Boot Logging text is recorded in the Ntbtlog.txt file in the %SystemRoot% folder.
• Starts Windows Normally: This option starts Windows in its normal mode.
• Reboot: This option restarts the computer.
• Return to OS Choices Menu: On a computer that is configured to starting to more than one operating system, this option returns to the Boot menu.
