Automatically Boot into Safe Mode

This batch file will backup your current boot.ini file, then add two safe mode options to your boot.ini file.
One is the same you would get when pressing F8 and choosing Safe Mode, the other is the just the minimal safe mode with no logging or display of drivers.
Copy the text in the code block into Notepad and save the file on your desktop as addsafe.bat (Be sure to change the Save as Type box in Notepad's Save dialog to All Files)
Double click the file to add the Safe Mode options.
Double click again to remove them.
