To resolve this problem, use one or more of the following methods.

Method 1: Verify that the partition is compatible with Windows

You cannot install Windows on a FAT32 partition. Additionally, you must correctly configure dynamic disks for use with Windows. To verify that the partition is compatible with Windows Vista, Windows 7 or Windows Server 2008 R2, follow these steps:

1. 1. For a dynamic disk that has a simple volume, use the Diskpart.exe utility to configure the disk as an active disk. For more information about how to use the Diskpart.exe utility, click the following article number to view the article in the Microsoft Knowledge Base:

2. 1. For a FAT32 partition, reformat the partition, or convert the partition to an NTFS file system partition by using the Convert.exe command. 
   1. Note When you format a partition, all data is removed from the partition. This data includes all the files on the partition. For more information about how to use the Convert.exe command, click the following article number to view the article in the Microsoft Knowledge Base:

Method 2: Update the drivers for the hard disk controller

If you want to install Windows Vista Windows 7 or Windows Server 2008 R2 as an upgrade, update the drivers for the hard disk controller to the latest drivers. 

Note Windows Setup provides a feature to migrate current drivers to the new operating system. Therefore, Windows Setup may use the drivers that are currently installed on the computer. If the computer does not have the latest drivers installed, the Setup program may use the outdated drivers. In this case, you may experience compatibility problems.

Method 3: Provide the correct drivers for the hard disk controller

If you are trying to perform a clean installation of Windows, you must provide the correct drivers for the hard disk controller. When you are prompted to select the disk on which to install Windows, you must also click to select the Load Driver option. Windows Setup will guide you through the rest of the process.

Method 4: Examine the Setupact.log file to verify that the partition is active

If you receive the following error message, verify that the partition is active by examining the Setupact.log file: Windows is unable to find a system volume that meets its criteria for installationNotes

• If you install Windows Vista, Windows 7 or Windows Server 2008 R2 as an upgrade, the Setupact.log file is located in the Drive:\$WINDOWS.~BT\Sources\Panther folder. Driverepresents the drive that contains the existing Windows installation.
• If you perform a clean installation of Windows Vista, Windows 7 or Windows Server 2008 R2, the Setupact.log file is located in the Drive:\$WINDOWS\Sources\Panther folder.Drive represents the DVD drive that contains the Windows Setup files.

To verify that the partition is active, follow these steps:

1. Insert the DVD into the DVD drive.
2. On the disk selection screen, press SHIFT+F10. A Command Prompt (CMD) window opens.
3. Change the directory to locate the Setupact.log file, and then open the Setupact.log file.
4. Locate the "DumpDiskInformation" section. This section contains information about partition mapping.
5. 1. In the "DumpDiskInformation" section, locate the log entry that resembles the following:
   1. Disk [0] partition [1] is an active partition
6. 1. If this log entry appears after an entry that resembles the following, the hard disk may not be configured to use a Windows-based operating system:
   1. Unknown
7. 1. In this case, use the Diskpart.exe utility to configure a different partition as active. 
   1. Note This step prevents a third-party operating system from starting.
8. Close the Command Prompt window.

Method 5: Check for firmware updates and for system BIOS updates

For firmware updates and for system BIOS updates, contact the manufacturer of the hardware in the computer, visit the following Web site:

Method 6: Verify that the system BIOS correctly detects the hard disk

For information about how to verify that the system BIOS correctly detects the hard disk, contact the manufacturer of the computer hardware.

Method 7: Use the Chkdsk.exe utility to check for problems

Method 8: Use the Diskpart.exe utility to clean the disk, and then run Windows Setup again

If you have tried all the methods that are listed in this section and the problem persists, use the Diskpart.exe utility to clean the disk, and then run Windows Setup again.
