SYMPTOMS
When you use the Express Install option to install Microsoft Windows Server 2003 from the installation CD, only half of the available drive space on the first logical drive is allocated to the operating system. The rest of the drive is unallocated.

Note The Express Install option is available only if Emergency Management Services is enabled in the BIOS of the computer.



CAUSE
This behavior occurs because the Express Install option is designed not to use all the available drive space for the system partition.



WORKAROUND
To work around this behavior, use either of the following methods:
 * Use the Custom Install option to install Windows Server 2003 from the installation CD.
 * Disable Emergency Management Services in the BIOS before you install Windows Server 2003 from the installation CD. After Setup is finished, re-enable Emergency Management Services in the BIOS.

When you use either of these methods, you are presented with the option to customize the partition that is used for the system partition.



Technical support for x64-based versions of Microsoft Windows
Your hardware manufacturer provides technical support and assistance for x64-based versions of Windows. Your hardware manufacturer provides support because an x64-based version of Windows was included with your hardware. Your hardware manufacturer might have customized the installation of Windows with unique components. Unique components might include specific device drivers or might include optional settings to maximize the performance of the hardware. Microsoft will provide reasonable-effort assistance if you need technical help with your x64-based version of Windows. However, you might have to contact your manufacturer directly. Your manufacturer is best qualified to support the software that your manufacturer installed on the hardware.
