256986 Description of the Microsoft Windows registry



SYMPTOMS
You use Windows Vista or Windows Preinstallation Environment (Windows PE) 2.0 to create partitions on a hard disk. After you do this, you try to install Microsoft Windows XP on the hard disk without using Windows XP to repartition the disk. In this case, you cannot install Windows XP successfully.

Windows XP Setup successfully completes the text-mode part of Setup. However, after the text-mode part of Setup is complete, the computer cannot be restarted successfully to enter the graphical user interface (GUI)-mode part of Setup. Additionally, the computer may stop responding. You may receive an error message that resembles one of the following:

A disk read error occurred

Unable to load operating system

Error loading operating system

When you deploy a Windows XP Professional sysprep image to a system, the system may continuously restart after you start the system for the first time. If you press F8 and then disable the &quot;automatic restart&quot; option, you may receive the following Stop error:

Stop: 0x000000ED (0X81F85678, 0xC000014F,0x00000000,0x00000000)

Unmountable_boot_volume

Additionally, if you view the disk in Windows PE 2.0, the disk may appear as &quot;raw.&quot;



CAUSE
This problem occurs because Windows Vista and Windows PE 2.0 create disk partitions differently than Windows XP. This problem occurs only on computers that use certain BIOS firmware.



WORKAROUND
To work around this problem, use one of the following methods.

Method 1: Disable the &quot;automatic disk translation&quot; feature
Before you partition the hard disk, you can disable the &quot;automatic disk translation&quot; feature in the BIOS configuration. For example, you can change the disk type from Auto to Large.

Method 2: Modify the registry to use the Windows XP disk partition procedure
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

Before you partition the hard disk in Windows Vista or in Windows PE 2.0, modify the registry so that the partitions are created by using the Windows XP procedure. To do this, follow these steps:  Click Start, click Run, type regedit, and then click OK. Locate and then click the following registry subkey:

HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\SERVICES\VDS\ALIGNMENT

 On the Edit menu, point to New, and then click DWORD value. Type LessThan4GB as the new entry name. Right-click LessThan4GB, and then click Modify. In the Edit DWORD Value dialog box, click Decimal.</li> In the Value data box, type 0, and then click OK.</li> Repeat steps 3 through 7 to add the following registry entries: <ul> Between4_8GB</li> Between8_32GB</li> GreaterThan32GB</li></ul>

Each registry entry must have a value of 0.</li> Exit Registry Editor.</li></ol>
