Few days back I posted the following message:
I have installed Win XP SP2 then Windows Server 2008 everything is working fine. After I have downloaded WinXP SP3 and installed it. My dual-boot is no longer working. How can I get back the Windows Server 2008?

Please read for example this article http://www.setup32.com/resource-guides/windows-vista/how-to-dualboot-vista-and-xp-with-vista-.php, section "Restoring Vista and dual booting" – should be similar (if not the same) for Windows 2008.
I just downloaded EasyBCD and re-written the MBR and it works.
