Windows XP in Grub 2

When I installed Debian 6.0 (Squeeze) on my laptop, I found that Debian Installer had not added Windows XP entry in the GRUB 2. You might also face same issue, then you can add following lines in /boot/grub/grub.cfg

## (1) Windows XP in /dev/sda1
menuentry "Windows XP" {
    set root=(hd0,1)
    chainloader +1
}

Here are few tips how to set root in the grub.cfg
