Windows 7 64 bit on a macbook 2.1 ????

I have a white macbook 2.1 I think that its early 2007. i recently put lion on it but now i want to try the developer preview for windows. I have a legitimate copy of windows 7 but it is the 64 bit version. I see some people say yes and some people say no.... something about 2 different disk??? I am not completely stupid when it comes to stuff like this.. I have jailbroken my phone and stuff but i cant seem to get this to work.. i think that i have made a partition.. when the machine reboots it goes to a black sreen that says cd1 and cd2 or something like that. i dont know how to make it run the dang disk =( i dont want to take a copy off the net but i am so desperate at this point dont know what to do. Please help. It seems like it is something so simple but then again the partition part wasnt that "easy" either. thanks in advance!!! i always seem to get great help on here. hope for a soon response =)
