Using LKGC, you can recover from problems such as a newly added driver that may be incorrect for your hardware. The LKGC feature does not solve problems caused by corrupted or missing drivers or files. To start the server with the LKGC: 1. Click Start > Shutdown > Restart, and then click OK. 2. When prompted to choose the instance of Windows to boot, press F8 (GUI console) or Esc 8 (headless server console). To enter Esc 8, press and release the Esc key and then within 2 seconds, press and release the 8 key. 3. Use the arrow keys to select Last Known Good Configuration, and then press Enter. 4. If you are running other operating systems on the server, select Microsoft Windows Server 2008 from the list, and then press Enter. If you were able to start your server using LKGC, the last change that you made to the server (for example, the installation of a driver) might be the cause of the startup problem. To recover from the problem, either remove or update the driver or program, and then test Windows for correct startup. Examine the system logs for information about why previous boots failed. Right-click My Computer, select Manage, and click on Event Viewer to see Application, Security, and System logs. NOTE: When you select LKGC, only the HKLM\System\CurrentControlSet registry settings are restored. All other registry keys remain unchanged, so if failure is related to application files or registry entries, the LKGC feature does not solve the problem. Safe Mode When you start the server in Safe mode, Windows loads a minimal set of drivers and services. Use Safe mode to identify and resolve problems caused by faulty drivers, programs, or services that start automatically. If the servers starts in Safe mode but not in normal mode, the system may have a conflict with the hardware settings or the resources. There might also be incompatibilities between programs, services, or drivers, or there might be registry damage. In Safe mode, you can disable or remove a program, service, or device driver that prevents the server from starting. To start the server in Safe mode: 1. Click Start > Shutdown > Restart, and then click OK. 2. When prompted to select the operating system to start, on a GUI console, press F8, or on a headless console, Esc 8. 3. Use the arrow keys to select Safe Mode, and then press Enter. 4. If you are running other operating systems on the server, select Microsoft Windows Server 2008 from the list, and then press Enter. If the server does not start in Safe mode, try starting it using the Recovery Console (see "Recovery Console" (page 16)). If you still cannot start the computer, look for possible hardware problems, such as defective devices, installation problems, cabling problems, or connector problems. Remove any newly added hardware, and then restart the server. If the server does start in Safe mode, use the following tools to troubleshoot the problem: • Event Viewer: The event logs in Event Viewer can help you identify and diagnose the cause of the startup problem. To start the Event Viewer, click Start > Administrative Tools > Event Viewer. In the Event Viewer, click the System log or the Application log to view the events recorded in the logs. • System Information: The System Information tool displays a comprehensive view of the computer's hardware, system components, and software environment.
