El Capitan boot camp assistant will fail to remove your Windows partition if you don't want that Windows installation. And you will likely end up with backing up your Mac OS X and format the whole disk to bring everything back to normal. However, it would appear that the only option offered in boot camp assistant is to install Windows 7. My assumption is that Windows XP can only be installed via boot camp if I have a much older OSX version installed, 10.6. Or, if by chance the boot camp assistant from 10.6 (3.x) can be installed in El Capitan.
