BootCamp: Windows 7 wont boot!

ok, yesterday, i installed windows 7, but at the end of the installation where it said "finallizing installation" the screen blacks out and the macbook crashes...
Then when i boot up in windows 7, there is a black screen with a tiny gray "_" flashing in the top left corner. The wierd thing is when i boot off the bootcamp partition in parallels, everything works fine... I am using a macbook 5,2 (may 2009) model running leopard. Any suggestions?

well, windows xp works fine for me...

now that u mention it

well, i did buy it off the streets in china so its probably fake ... ill try waiting a few minutes and see what happens

Nope, still not working... waited 10 minutes...

well, windows 7 boots fine in parallels via bootcamp... y doesnt it boot in bootcamp?
