Windows XP installation in Pavilion DV6

I am having a Pavilion dv6-3019tu Notebook with Windows 7 (Home Edition 64bit) installed.

Now i would like to install Windows XP from a CD which has the iso image. In BIOS boot order i have changed the boot option as CD/DVD, but still Windows 7 boots and not from the CD.

Please help me in installing Windows XP in my notebook.

Thanks in advance.
