A+: Advanced Boot Options and the Windows GUI

Options to help diagnose and troubleshoot the Windows GUI:    .

    • Enable Boot Logging— Creates a ntbtlog.txt file.

    • Enable low-resolution video (640 × 480)— Uses a standard VGA driver in place of a GPU-specific display driver, but uses all other drivers as normal. (This is called Enable VGA Mode in Windows XP/2000.)

    • Last Known Good Configuration—Starts the system with the last configuration known to work; useful for solving problems caused by newly installed hardware or software.

    • Directory Services Restore Mode— This is used to restore a domain controller’s active directory (Windows Server). Even though it is listed, it is not used in Windows Vista/XP/2000.

    • Debugging Mode— This is an advanced diagnostics tool that enables the use of a debug program to examine the system kernel for troubleshooting.

    • Disable automatic restart on system failure (Vista only)— Prevents Windows from automatically restarting if an error causes Windows to fail. Choose this option only if Windows is stuck in a loop where Windows fails, attempts to restart, and fails again.

    • Disable driver signature enforcement (Vista only)— Allows drivers containing improper signatures to be installed.

    • Start Windows Normally— This can be used to boot to regular Windows. This option is listed in case a user inadvertently presses F8, but does not want to use any of the Advanced Boot Options.
