Situation:
This document describes partition table problems that are associated with viruses.

Solution:
If partition changes made under one operating system are not reflected under another, and vice versa, a master boot record (MBR) virus may be present.

Use a virus check utility that can detect the latest viruses, such as Norton AntiVirus. If a virus is found, data loss is likely. Before removing the virus, boot each operating system and use the Check for Errors operation to evaluate the integrity of the partition. Back up the files on any partition that passes the Check for Errors operation. Then remove the virus and perform the Check for Errors operation on the partitions again. Delete and recreate any partitions that fail the check. Finally, reinstall the operating systems and restore the backup files as necessary.
