Which boot option can you use to move system boot logs from a failing computer to another computer for evaluation?
1. Recovery Console
2. Debugging Mode
3. Safe Mode with Networking
4. Enable Boot Logging
Explanation : Debugging Mode gives you the opportunity to move system boot logs from the failing computer to another computer for evaluation. To use this mode, you first must connect the failing computer to another computer using a serial cable. You then can review the boot logs on a functioning computer.
Safe Mode with Networking is the same as Safe Mode, but the drivers necessary to access the network are loaded. This is useful if you need to access the network to download replacement drivers.
The Enable Boot Logging option allows the system to boot normally while recording all files loaded during the boot process. The log is recorded in a file named NTBTLOG.TXT. The log will identify which drivers loaded and which failed. This is especially helpful if you have a copy of the NTBTLOG.TXT file that was created before there was a problem. You then could compare them to see what has changed.
The Recovery Console does not start the graphical interface, but it does allow you to access any FAT16, FAT32, and NTFS file systems. The purpose of the Recovery Console is to allow you to repair a damaged registry, system files, or file system on the hard drive.

Operating Systems: Dealing corrupt OS file
A user's computer cannot boot because an operating system file is corrupt.
What should you try first to resolve the problem?
1. Boot to Safe Mode and use System Restore.
2. Boot to Recovery Console and use System Restore.
3. Boot to Recovery Console and run Chkdsk.
4. Boot to Safe Mode and run Chkdsk.
Explanation : You should boot to Recovery Console and run Chkdsk. Because an operating system file is reported as corrupt, you will need to boot to Recovery Console. To do so, insert the Windows XP installation disc and choose R when prompted whether you want to install Windows XP or repair an existing installation. Next, run Chkdsk with the /r option to locate bad sectors and repair the file. If that does not work, you will probably need to reinstall Windows or restore from backup.
You cannot boot to Safe Mode because an operating system file is corrupt. Safe Mode loads a minimum set of drivers, but it still requires that the operating system files be valid.
You cannot use System Restore from Recovery Console. System Restore requires Windows XP. Also, System Restore is used to recover from configuration problems caused by installing applications or updating drivers. It does not perform a check disk.

Operating Systems: PC won't boot after a configuration change
A user makes some configuration changes and then installs an application. The application requires the user to reboot the computer. When the computer reboots, it is unable to start Windows XP.
You need to ensure that the user's data is preserved.
What should you try first?
1. >>Start in Safe Mode and perform a System Restore.
2. Use the Emergency Repair Disk.
3. Perform Automated System Recovery.
4. Start the system in VGA mode and uninstall the application.
Explanation : You should start the computer in Safe Mode and perform a System Restore. Windows XP saves a scheduled restore point, a restore point before making some configuration changes, and a restore point before an application is installed. It allows you to revert your computer's configuration to a specific point in time. Restoring a system using System Restore does not affect user data. You can initiate System Restore by booting normally or to Safe Mode. In this case, you will need to boot to Safe Mode.
You should not start the system in VGA mode and uninstall the application. VGA mode is used specifically to correct problems with the video adapter configuration. Also, uninstalling the application might not resolve the problem because the problem might be caused by one of the configuration changes.
You should not use Automated System Recovery (ASR). ASR reformats the hard disk and restores from an ASR backup set, which does not include user data. Therefore, user data would be lost.
You cannot use an Emergency Repair Disk (ERD). ERDs were supported by Windows NT and Windows 2000. They are not supported by Windows XP.

Operating Systems: Starting the PC without launching specific startup applications
You are troubleshooting a computer running Windows XP. You want to start the computer without launching specific startup applications. Aside from that change, you want the computer to boot normally.
What should you do?
1. Start the computer in Safe Mode.
2. Remove all shortcuts from the C:\Documents and Settings\All Users\Start Menu\Programs\Startup folder.
3. >>Use Msconfig to disable the startup applications.
4. Start the computer in Safe Mode with Networking.
Explanation : You should use Msconfig, also known as the System Configuration Utility, to disable startup items. Msconfig allows you to select which items load at startup, including which .ini files are loaded and whether all, none, or only selected startup applications are loaded. Using Msconfig is a good way to troubleshoot problems related to startup or devices and applications that load at startup. You can also view which services are running.
You should not start the computer in Safe Mode. Safe Mode loads only the minimum drivers needed to run the operating system.
You should not remove all shortcuts from C:\Documents and Settings\All Users\Start Menu\Programs\Startup folder. While this is the folder that stores shortcuts to the applications that run at startup for any user who logs onto the computer, it does not contain the user-specific shortcuts. Also, it is best not to remove the shortcuts because you will just have to reconfigure them later. Also, some startup applications are not configured through the Startup folder. Instead, they are configured through the registry.
You should not start the computer in Safe Mode with Networking. Safe Mode with Networking loads only the minimum drivers needed to start the operating system and access the network.

Operating Systems: Safe Mode vs Debugging Mode vs VGA Mode vs Last Known Good Config
You are troubleshooting a problem with a Windows XP Professional computer. The system will not start normally. The owner said all she did was download and install a program off the Internet. When she rebooted, the system hung at the Windows logo screen.
You have tried to use the Last Known Good Configuration but the system still fails to boot to the desktop.
How should you attempt to start the system to correct the error?
1. Debugging Mode
2. Safe Mode with Command Prompt
3. >>Safe Mode
4. Enable VGA Mode
Explanation : If using the Last Known Good Configuration does not correct a boot up problem, Safe Mode should be used. Safe Mode boots the operating system with a minimum configuration, and can be used to solve problems with a new hardware or software installation, or problems caused by user settings. Safe Mode boots with the mouse, basic video, keyboard, and mass storage drivers loaded. It uses the default system services (not any extra services) and does not provide network access. It does provide a graphical interface. With the graphical interface enabled, you can use the normal Windows tools and utilities to correct the problem.
Safe Mode with Command Prompt is the same as Safe Mode but does not load the graphical interface. Many standard Windows tools and utilities do not run without the graphical interface.
Enable VGA Mode is used when the video setting is such that you cannot see the screen well enough to fix a bad setting. This can happen if a user creates a desktop with black fonts on a black background, or something similar to that. Booting in this mode gives you very plain VGA video display but allows you to change the settings in the Display properties.
Debugging Mode gives you the opportunity to move system boot logs from the failing computer to another computer for evaluation. To use this mode, you first must connect the failing computer to another computer using a serial cable. You then can review the boot logs on a functioning computer.

Operating Systems: Safe Mode and Recovery Console
What would be the next logical step in the repair process if a Windows XP computer fails to start in Safe Mode with Command Prompt Mode?
1. Safe Mode with Networking
2. Enable VGA Mode
3. Last Known Good Configuration
4. >>Recovery Console
Explanation : If booting a system using Safe Mode with Command Prompt fails, you should use the Recovery Console. The Recovery Console does not start the graphical interface, but it does allow you to access any FAT16, FAT32, and NTFS file systems. The purpose of the Recovery Console is to allow you to repair a damaged registry, system files, or file system on the hard drive.

Safe Mode with Networking is the same as Safe Mode, but the drivers necessary to access the network are loaded. This is useful if you need to access the network to download replacement drivers.
Windows NT, 2000, and XP all keep a copy of the Last Known Good Configuration in the registry. If something is configured incorrectly, you can restore the settings used for the last successful boot using the Last Known Good option. Any settings changes made since the last successful boot will be lost.
