Install Windows XP along with Windows 2003 - dual boot

[kiran.gandhi]

Hi,
I have installed Windows 2003 in D: partition and Windows Vista on C:. Later I removed Windows Vista (using VistaPro utility) from C: and Windows 2003 is working fine. Now I am trying to install Windows XP on C: but it gives error. I tried few times but it is failing same. Can somebody help me installing Windows XP as dual boot along with Windows 2003 if it is supported?

Thanks
Kiran
