problem with install windows xp on mac book pro

hi all
I'm confuse now because i install windows many time on my mac book but now i don't know why after instal part 1 when you have to restart your mac to going to next section there is not any file in my partition ! and dose tell me you have to find or something like that : \system32\hal.dll. I don't know what the hell is going with windows . i hate windows but unfortunately i must have windows to run my software .

If anybody knows what should i do please help me cause i need to finish my project for my university . i tried more than 20 times today and i reinstall my mac os 2 times and i have 5 different version of windows . at the moment i have os leopard (its really nice and fast) .
I'm waiting for your kindly help .

cheers
