Stuck with Safe Mode?

So I was messing around with logonui.exe and messed something up. I needed to go into safe mode to fix it. The problem is the logon screen is messed up. If there's only one user, there's no problem. That is the case for normal mode. But in safe mode there's 2 users, and so it gets stuck at the logon screen. Now I need a way to edit boot.ini to take that safemode flag out. How?

You could try Ctrl+Alt+Del twice on the logon screen. Takes you to the traditional text box login, a la Windows 2000.
