Help my vista laptop has locked me out, my bro tried to speed it up for me and now I am locked out, it is asking for passwords and usernames that I didnt set up, I can only get into it on safe mode, there is a techguys restore disc that you can burn off on the startup menu, but it wont let me do this in safe mode, also if you start up and press f8 there is supposed to be an option to repair your computer there, but it is missing,I have been told that this is a common problem on vista, and if you search google and state, repair your computer option is missing, that there should be a fixit disc that I can download, but I am not sure what I am looking for and dont want to make a bad situation worst, any help would be really appreceated.thanks
