Just wanted to change the startup noise.
I spent 2 hours trying Brinks way, multiple times, and never got it to work. I decided to try Heiji's way and the first time I restart my computer...
I come to a black screen that says Windows 7, has shutdown options and assisted access options (on-screen keyboard, etc.) and THAT'S IT.
I wouldn't call myself a computer whiz, I do know my way around PC's and am fairly savvy at using them. It is hard to look back and see that by changing a file's name has now blocked all access to my computer (~500gigs of stuff for school, projects, entertainment and more).
I've tried every option within boot menu and none of the safe modes take me anywhere. My computer is now royally f-ed.
I suggest you remove Heiji's post before someone else does this as well.
