Warning: Do not install Windows XP directly on a PC with Windows Vista preinstalled.

It is well known that Microsoft has adopted a new system startup management mechanism and a new BootLoader in Windows Vista. It is different from Windows. NT has included ntldr used in Windows 2000 /XP /2003, so installing Windows XP directly on a PC with Windows Vista pre-installed will destroy the Windows Vista Boot Loader, as we said in the Windows Vista installation tutorial:
