In Microsoft Windows XP Professional, you can perform most disk administrative tasks, both local and remote, by using the Microsoft Management Console (MMC) snap-in tool called Disk Management, which can be used to convert disks, as well as format current partitions and unallocated space. You can also check on the status of fixed and removable disks and their associated properties.
To open the Disk Management MMC, you can select Start, right-click My Computer, and then click Manage, which will open the Computer Management MMC. Under the Storage icon, click Disk Management to open the Disk Management MMC.
You can also type compmgmt.msc in the RUN box or from a command line to launch the Computer Management MMC.
If that doesn't work... try FIXMBR
FORMAT: fixmbr device name
Use this command to repair the master boot record (MBR) of the boot partition. In the command syntax, device name is an optional device name that specifies the device that needs a new MBR. Use this command if a virus has damaged the MBR and Windows cannot start.
WARNING: This command can damage your partition tables if a virus is present or a hardware problem exists. Using this command can result in inaccessible partitions. Microsoft recommends that you run antivirus software before you use this command.
You can obtain the device name from the output of the map command. If you do not specify a device name, the MBR of the boot device is repaired, for example:
If FIXMBR detects an invalid or non-standard partition table signature, FIXMBR prompts you for permission before rewriting the MBR. FIXMBR is supported only on x86-based computers.
