I had the same problem its the hardrive. It is caused due to the hardrive boot sector.

Wenn die Fehlermeldung nach dem Neuinstallieren von Windows XP auftritt ist das Anti-Virenprogramm (nicht von Microsoft) noch aktiv gewesen. Windows XP kommt bei der Neuinstallation mit fremden Anti-Virusprogrammen in konflikt und gibt diese Fehlermeldung raus. Deshalb empfehle ich vor der Neuinstallation von Windows XP auf jeden Fall das Anti-Virusprogramm zu deaktivieren oder zu deinstallieren. Sollte diese Fehlermeldung nach einem Neustart mit vorangegangenem Betriebsfehler (Abstuz, Hängter etc) gekommen sein, dann ist mit großer Warscheinlichkeit die Festplatte defekt.
