SYMPTOMS

You cannot install or start Windows Vista when the volume of the system partition is larger than 2 terabytes (TB).

Back to the top

CAUSE

This issue occurs for one of the following reasons:

• You configure the master boot record (MBR) disk as the boot partition.

When the MBR disk is used as the boot partition or as the data partition, 2 TB is set as the size limit for the MBR disk. For more information about the size limit for the MBR disk, visit the following Microsoft Web site:

http://www.microsoft.com/whdc/device/storage/LUN_SP1.mspx (http://www.microsoft.com/whdc/device/storage/LUN_SP1.mspx)
• You configure the GUID partition table (GPT) disk as the boot partition.

When you start an operating system from a GPT disk, the Extended Firmware Interface (EFI)-based BIOS is required. However, the EFI-based BIOS is not supported in Windows Vista 32-bit editions. Additionally, it is not supported in Windows Vista 64-bit editions unless you install Windows Vista Service Pack 1 (SP1).

Note There is no 2-TB limit if the GPT disk is used in a data partition.

For more information about EFI and Windows Vista, visit the following Microsoft Web site:
