Ich zitiere mal aus der "Microsoft Windows XP Professional Resource
Kit Documentation", was deiner Aussage deutlich widerspricht:

| Avoid Using the Fixmbr Command to Treat Viruses

| The Recovery Console, a troubleshooting tool in Windows XP Professional,
| offers a feature called Fixmbr. However, it functions identically to the
| Fdisk /mbr command, replacing only the master boot code and not affecting
| the partition table. For this reason, it is also unlikely to help resolve
| an infected MBR.

Oder auch hier:

| Restoring the MBR
[...]
| Use the Recovery Console.

| You can use the fixmbr command in Recovery Console to repair the MBR.
| You can start Recovery Console by booting from the Windows XP Professional
| operating system CD; so this troubleshooting method is available even
| if Windows XP Professional does not start in normal or safe mode.
| *However, you cannot use Recovery Console to repair partition tables that
| were damaged by viruses or other corruption.*
[...]
| Using the Recovery Console to Replace the MBR
| You can use the fixmbr command in Recovery Console to rewrite the MBR
| to resolve a corrupted MBR on a startup disk. However, running fixmbr
| overwrites only the master boot code, leaving the existing partition
| table intact. If the corruption in the MBR affects the partition table,
| running fixmbr might not resolve the problem.

Zur Reparatur der Partitiontabelle brauchts IMHO z.B. einen Diskeditor.
