Safe Mode - HP Integrity Superdome SX1000 Recovery Manual

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.
