Problem while installing Windows on a MAC

I have tried to install Windows XP Pro with Bootcamp but the system keeps "installing" Windows but always comes back to the same blue sreen called "Welcome to Windows Installation". Also it doesn't ask me to choose between FAT, NIFS, etc I don't even know if I still have MAC OS running as the computer gets stuck at the blue screen, no matter how many times I restart. Can you help by any chance?
Thank you SO MUCH
Linda

How about telling us what kind of XP Pro CD you're using to install? And have your read thru the Boot Camp Assistant instructions? They're included with Boot Camp as a PDF file.

The XP CD must be either a Microsoft boxed full install or a System Builder's full install version. And it must be SP2 or SP3, not SP1 or less.

In other words, branded versions will not work (Sony, Dell, Toshiba, HP, etc.). Also, recovery and restore versions will likewise not work. And lastly, any kind of multiple licensed version will not work.
