i installed bootcamp / win7 on my imac at home with discs that shipped with the computer. however, my 17" macbook pro (late 2010) discs were lost by my IT guy. he ordered replacements, but there is no executable file anywhere on the new disc. apple support assures me the necessary files are on it. the disc says 17inch MacBook Pro, Mac OSX Install DVD, but there are no bootcamp files on it anywhere i can find. any tips?
