In cases where computer has more than one operating system, use the arrow keys to highlight the operating system you wish to boot in safe mode, and then press F8.
Whether using one and more than one operating system, you can choose the safe mode option on the Advanced Boot Options screen. The safe mode options include Safe Mode, Safe Mode with Networking, and Safe Mode with Command Prompt. In addition, you need to log on with a user account that has administrator rights.
Windows users can use safe mode to troubleshoot problems with programs and drivers that are not starting correctly or that prevent Windows from starting. If a recently installed program, device or driver prevents Windows from starting or running correctly, you can remove the program in safe mode. You can also use Windows 7 tools in safe mode, such as Recovery, Device Manager or Event Viewer, to identify, troubleshoot and remove the programs or drivers causing problems.
You can also make the necessary settings for accessing Safe Mode from a normal Windows session. To do so, first press the Windows key and R together to open the Run window, type "msconfig" in the Open field, and click OK. In the System Configuration window that appears, click on the Boot tab, navigate to the Boot Options section, and check the box for Safe Mode. Check Minimal under the Safe Mode options, click Apply, click OK, and then restart your computer. With this method, however, you must access the System Configuration options from within Safe Mode and select Normal Startup to boot back into Windows 7 in the normal mode.
Before restarting your computer, ensure you're removed all external devices such as CDs, DVDs and floppy disks.Learn more about Computer Help
