If you want to start Windows 7 in safe mode do the following:

1. Reboot your computer
2. Right before the Windows 7 splash screen start tapping the F8 key on your keyboard
3. Once you see the advanced boot options screen use the arrow keys to get to Safe mode and press Enter

If you do not see the advanced boot options and Windows 7 continues to load normally, then simply restart and try again.

If tapping the F8 key doesn’t work disable the no GUI boot up option:
. Click the start button
. Type msconfig in the search box
. Press Enter
. Open the Boot tab
. Disable the no GUI boot option

Now you can try one more time rebooting your computer and tapping the F8 key.

Another way to start Windows 7 in safe mode is to:
. Type msconfig in the search box
. Press Enter
. Open the Boot tab
. Choose Safe mode and select one of the four different options: Minimal, Alternate Shell, Active directory repair, Network, press the OK button and restart your computer.
