Workaround For Rebooting To Safe Mode In XP:

Sometimes the common method for rebooting to Safe Mode are impossible, like if you have a USB keyboard. (The common method is restarting and pressing F8, or some other key, at the right moment.) To configure XP so its next restart will enter Safe Mode, launch the System Configuration Utility (START, RUN, msconfig), click the BOOT.INI tab and check the box titled /SAFEBOOT. Don’t touch the other settings. When you reboot, XP will restart in Safe Mode and will keep doing so until you uncheck that box.
