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.

Best practices for resolving partmgr issues

A clean and tidy computer is the key requirement for avoiding problems with partmgr. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the partmgr.sys process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
