Repair Your Computer	Shows a list of system recovery options that you can use to repair startup problems, run diagnostics, or restore your system. If Repair your computer isn't listed as an option, then your computer doesn't include preinstalled recovery options, or your network administrator has turned them off. You could also boot from a retail Windows 7 installation disc to see the System Recovery Options.
Safe Mode	This starts Windows 7 with a minimal set of drivers and services. Safe mode is a troubleshooting option for Windows that starts your computer in a limited state. Only the basic files and drivers necessary to run Windows are started. The words "Safe Mode" appear in the corners of the display to identify which Windows mode you are using. If an existing problem does not reappear when you start in safe mode, you can eliminate the default settings and basic device drivers as possible causes. If you don't know the cause of the problem, you can use the process of elimination to help you find the problem. Try starting all of the programs you commonly use, including the programs in your Startup folder, one by one, to see if a program might be the cause of the problem. If your computer automatically starts in safe mode without prompting, a problem with your computer might be preventing Windows from starting normally. If you think the cause of the problem might be a recently installed program or device, try using System Restore
Safe Mode with Networking	This starts Windows 7 in safe mode and includes the network drivers and services needed to access the Internet or other computers on your network. . You should choose this option if you think you may need to access the Internet or your local network while troubleshooting in Safe Mode.
Safe Mode with Command Prompt	This starts Windows 7 in safe mode with a command prompt window instead of the usual Windows interface. To exit from here, press Ctrl+Alt+Delete or type Exitand press Enter. This option is intended for IT professionals and administrators.
Enable Boot Logging	Creates a file named ntbtlog.txt, that lists all the drivers that are installed during startup and that might be useful for advanced troubleshooting.
Enable Low Resolution Video (640 X 480)	Starts Windows 7 using your current video driver and using low resolution and refresh rate settings. You can use this mode to reset your display settings, or to use a television monitor with your computer if needed.
Last Know Good Configuration (advanced)	Starts Windows 7 with the most recent registry and driver configurations that worked successfully. Every time you turn your computer off and Windows 7 shuts down successfully, important system settings are saved in the registry. You can use those settings to start your computer if a problem occurs. For example, if a new driverfor your video card is causing problems, or an incorrect registry setting is preventing Windows 7 from starting correctly, you can restart your computer using Last Known Good Configuration.
Directory Services Restore Mode	Starts Windows 7 domain controller running Active Directory so that the directory service can be restored. This option is intended for IT professionals and administrators.
Debugging Mode	Starts Windows 7 in an advanced troubleshooting mode intended for IT professionals and system administrators.
Disable Automatic Restart on System Failure	Prevents Windows 7 from automatically restarting if an error causes Windows 7 to fail. Choose this option only if Windows 7 is stuck in a loop where Windows 7 fails, attempts to restart, and fails again repeatedly.
