Introduction
This article describes the functionality restrictions of the Diskpart.exe utility that is included in Microsoft Windows Server 2003 and in Microsoft Windows XP.



MORE INFORMATION
The Diskpart.exe utility that is included in Microsoft Windows Server 2003 and in Microsoft Windows XP does not let you extend the Windows boot and system partitions into unallocated space.

The Diskpart.exe utility supports only the extension of data partitions. System or boot partitions may be blocked from being extended. You may receive the following error after you try to extend a system or boot partition:

Diskpart failed to extend the volume. Please make sure the volume is valid for extending.

The Diskpart.exe utility that is included with the Microsoft Windows 2000 Resource Kit may let you extend Windows 2000 boot and system partitions into unallocated space. However, the file system may not be extended, and when you try to extend boot or system partitions, your computer may stop responding.

Caution You may find that Microsoft Windows XP Service Pack 1 (SP1) lets you use the Diskpart.exe utility to extend Windows boot and system partitions. The boot and system partitions may be extended, but the file system may not be extended. Therefore, your computer may stop responding if you try to extend the boot and system partitions. The Diskpart.exe utility was not intended for extending Windows boot and system partitions.

Windows XP and Windows Server 2003 include the Diskpart.exe utility as part of the base operating system.
