I have Vista installed and now bought a new HDD and want to install Vista in the new HDD. After installation of Vista in the new partition I will have both installations in the Boot Manager. Now how can I remove the Vista from the old installation partition without loosing the other O/S (XP) and the new Vista? If I format the old partition then am sure I'll be having the error BootLdr missing. So I want to keep only XP and new Vista running and old Vista to be cleaned from the previous partition>?
