Just before the splash screen appears, press F8 to enter Advanced Boot Options. You’re presented with three variations of Windows Vista Safe Mode:
Safe Mode: This is the default option and is usually the best choice. This mode will load only the absolute minimum processes necessary to start Windows. Safe Mode with Networking: This option loads the same processes as Safe Mode but also includes those that allow the networking functions in Vista to work. You should choose this option if you think you may need to access the internet or your local network while troubleshooting in Safe Mode. Safe Mode with Command Prompt: This version loads a minimum set of processes but will allow immediate access to Command Prompt. This is a valuable option if more advanced troubleshooting is necessary.
Using the arrow keys on your keyboard, highlight either the Safe Mode, Safe Mode with Networking, or Safe Mode with Command Prompt option and press Enter. If you’re not sure if any of your personal accounts have admin rights, log in using your own account and see if it works.
