Windows 7 Advanced Boot Options Explained
Before I show you how to boot Windows 7 to safe mode, I want to briefly explain what each option in the advanced boot menu means.
Safe Mode option starts Windows with a minimal set of drivers and services. It loads just the drivers Windows 7 requires to start. This way, you can troubleshoot and determine what may be stopping Windows from starting.
Safe Mode with Networking
Windows 7 safe mode with networking starts Windows 7 with the basic drivers required to start but also includes network drivers.
This option is helpful if you need to install Windows update or update device drivers via the internet.
Safe Mode with Command Prompt
Loads only Windows 7 core drivers but instead of starting Windows 7 GUI, it loads Command prompt only.
Enable Boot Logging
This is one of the most important Windows 7 troubleshooting boot option. When this option is selected, a file called ntbtlog.txt is created. This files lists all the drivers that are installed at startup. This includes the last file that was loaded before a Windows 7 failure. Reviewing this file might be useful for advanced troubleshooting.
Enable low-resolution video (640×480)
Starts Windows in low-resolution display mode (640×480). This option will help you determine whether Windows 7 start problem was caused by your video driver.
Last Known Good Configuration (advanced)
This has bailed me out several times! If you installed a device driver or a software that caused your computer to crash, Last Known Good Configuration will start Windows with the last copy of registry and driver configurations that worked successfully. This option will save your computer most of the time!
Directory Services Restore Mode (DSRM)
This option is useful in Domain Controllers. Directory Services Restore Mode option allows advanced users to restore Active Directory.
Enables Windows kernel debugger and starts Windows in an advanced troubleshooting mode. This mode is intended for advanced users and administrators.
Disable automatic restart on system failure
This option will prevent Windows from rebooting automatically after a crash. This will stop your computer from rebooting repeatedly.
Disable Driver Signature Enforcement
By default Windows enforces driver signing – effectively stops drivers with improper signature from loading. If you installed a driver you are sure is not properly signed, you may select this option to allow the driver to load (not recommended).
Start Windows Normally
Selecting this option starts Windows in its normal mode.
