Chapter 23: Exploring the Windows Boot Environment
Using the System Conﬁguration Utility
Using the System Configuration utility (Msconfig.exe), you can set the default operat-
ing system and control the way your computer starts. For example, you can config-
ure the computer to start in Safe Mode or force the computer to use standard VGA
The basic steps for starting and using the System Configuration utility are as follows:
1. Click Start, type
msconfig.exe in the Search box, and press Enter.
2. Select the Boot tab, as shown in Figure 23-2.
3. To set the default operating system, click the operating system you want to use
and then click “Set as default.”
4. To start the operating system in Safe Mode for troubleshooting, select the “Safe
boot” checkbox and then set other troubleshooting options as appropriate.
5. Click OK to apply your changes.
If you are using the System Configuration utility for troubleshooting, you must later
remove your selective startup options. After you restart the computer and resolve any
problems, access the System Configuration utility again, select Normal Startup on
the General tab, and then click OK.
