Booting Issues

#1
I'm trying to boot Windows Xp Pro, Windows Vista & Fedora Core 6 and EasyBcd loads both versions of windows fine but it gives a blank screen when I try and load Fedora... What is it that I need to do to get everything to boot perfectly??? I think it might be something with the program thinking that linux is on my C or D drive when its not because both of those drives are for windows only...
