20. You installed a new game on a Windows XP computer, and the computer fails to restart. Which of the following methods can you use to fix this startup problem? A. Use the Last Known Good Configuration from the Advanced Boot menu. B. Use the Recovery Console to uninstall the new game. C. Use the last full backup tape to restore the system. D. Use an Emergency Repair Disk (ERD) to repair the startup files.
A is correct. You can use the Last Known Good Configuration from the Advanced Boot options to restore the system to the previous working configuration. You cannot use the Recovery Console to uninstall the game, nor can you do it using the last full backup tape. ERD will also not help. Moreover, ERD can only be used on Windows NT and Windows 2000 computers.
