SUMMARY

This article describes how to troubleshoot "Stop 0x0000007B" error messages that may occur on your Microsoft Windows 2000-based computer. In certain situations, you may receive an error message that is similar to the following on a blue screen on your Windows 2000-based computer:
***STOP 0x0000007B (parameter1, parameter2, parameter3, parameter4)
INACCESSIBLE_BOOT_DEVICE
The "Stop 0x0000007B" error message is a Windows 2000 Executive character-mode Stop error message. It can be caused by various issues. It may indicate that either a failure occurred during input/output (I/O) system initialization when the driver for the boot device initializes the device that Microsoft Windows is trying to start from, or that the file system did not initialize because it did not recognize the data that is stored on the boot device. This error message may occur in the following situations:
  • If Windows is installed on an unsupported disk or small computer system interface (SCSI) controller.
  • After the installation of a new SCSI adapter or disk controller.
  • When the disk was repartitioned with the system partition.
This article describes both general and specific troubleshooting steps that you can use when you receive this error message on your Windows 2000-based computer.

Note This article does not discuss how to troubleshoot "Stop 0x0000007B" error messages that occur during Windows 2000 Setup or when you install a Windows 2000 Setup. To troubleshoot "Stop 0x0000007B" error messages that may occur when you run Setup to install Windows 2000 or when you install a Windows 2000 service pack, click the following article number to view the article in the Microsoft Knowledge Base:
822051  (http://support.microsoft.com/kb/822051/ ) How to troubleshoot "Stop 0x0000007B" error messages that occur when you run Windows 2000 Setup

General troubleshooting procedures

Before you troubleshoot a "Stop 0x0000007B" error message, read the contents of this article to determine if any one of the specific issues that are listed later in this article applies to you. If they do not, use the following general troubleshooting steps:
  1. If you recently added new hardware, remove the new hardware or reconfigure it so that it does not conflict with the resources of any other installed controllers.

    If an IRQ or I/O port address conflict exists between the boot controller and another controller, Windows 2000 may display a "Stop 0x0000007B" error message. Check the Microsoft Hardware Compatibility List (HCL) to make sure that the hardware that you want to add and its drivers are compatible with Windows 2000. For more information about the HCL, visit the following Microsoft Web site:
    http://www.microsoft.com/whdc/hcl/default.mspx (http://www.microsoft.com/whdc/hcl/default.mspx)
    For information about the hardware that you want to install, contact the hardware manufacturer.
  2. Use the Last Known Good Configuration feature. Using the Last Known Good Configuration feature may resolve the problem if you recently installed a device driver that is incompatible with your boot controller.

    When you use the Last Known Good Configuration feature, you start your computer by using the most recent settings that worked. This feature restores registry information and driver settings that were in effect the last time that the computer started successfully. Use this feature when you cannot start Windows after you make a change to the computer (for example, if you install or you upgrade a device driver).

    To start the computer by using the Last Known Good Configuration feature, follow these steps:
    1. Restart the computer.
    2. Press F8 when you receive the following message:
      Please select the operating system to start.
    3. On the Windows Advanced Option menu, use the arrow keys to select Last Known Good Configuration, and then press ENTER.
    4. If you are running other operating systems on the computer, click Microsoft Windows 2000 from the list that appears, and then press ENTER.

      Warning After you start your computer by using the Last Known Good Configuration feature, changes that you made since the last successful startup are lost.

      If you can start your computer by using the Last Known Good Configuration feature, the last change that you made to the computer (for example, the installation of a driver) may be the cause of the problem. To troubleshoot a problem, you can either remove or update the driver, and then test Windows to determine whether the problem is resolved.
  3. Use an Emergency Repair Disk (ERD). If you have an ERD, use it to troubleshoot the problem. You can use the emergency repair process to repair the system files, the partition boot sector, and the startup environment.

    For more information about the emergency repair feature, click the following article number to view the article in the Microsoft Knowledge Base:

You receive a "Stop 0x0000007B" error message when you try to start your computer after you move the dynamic hard disk

When you start your Windows 2000-based computer, you receive the following Stop error message:
STOP: 0x0000007b (0xf881b84c,0xc0000034,0x00000000,0x00000000)
INACCESSIBLE_BOOT_DEVICE

0xc00000034 STATUS_OBJECT_NAME_NOT_FOUND

Cause

This error message may occur if the primary disk group identity of the hard disk does not match the primary disk group identity that is stored in the registry. This mismatch may occur if all the following conditions are true:
  • You configure the hard disk that contains the system partition as a dynamic disk on a computer that is running Windows 2000.
  • You remove the hard disk from the computer, and then install the hard disk in a second Windows 2000-based computer.
  • You import the hard disk to a disk group that contains dynamic disks on the second Windows 2000-based computer.
  • You return the hard disk from the second computer to the first computer.

Resolution

To resolve this problem, use Registry Editor to delete the Primary Disk Group registry key from the registry of the computer that does not start. To delete this key, follow these steps.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
322756  (http://support.microsoft.com/kb/322756/ ) How to back up and restore the registry in Windows
  1. Remove the hard disk that contains the system partition from the computer that does not start, install the hard disk in the second computer, and then start the second computer.
  2. On the second computer, click Start, click Run, type regedt32 in the Open box, and then click OK.
  3. In Registry Editor, click HKEY_LOCAL_MACHINE, and then on the Registry menu, click Load Hive.
  4. Locate, and then click the System file that contains the hive of the first computer's operating system.

    Note The System file is in the Drive:\Winnt\System32\Config folder, where Drive is the drive letter of the hard disk that is from the first computer.
  5. Click Open, type Temp in the Key Name box, and then click OK.
  6. Double-click HKEY_LOCAL_MACHINE, and then double-click Temp.
  7. Double-click ControlSet00n, where n is the number of the control set.
  8. Double-click Services, double-click dmio, and then click Boot Info.
  9. Right-click the Primary Disk Group registry key, and then click Delete.
  10. Repeat steps 7 through 9 for each instance of ControlSet00n that appears in the HKEY_LOCAL_MACHINE\Temp subkey.
  11. Click Temp, and then on the Registry menu, click Unload Hive, and then click Yes.
  12. Quit Registry Editor.
  13. Shut down the second computer, and then remove the hard disk that is from the first computer.
  14. Reinstall the hard disk in the first computer, and then start the first computer.
In Windows 2000, there can be only one dynamic disk group. When you move a dynamic disk from one computer to a second computer that already contains dynamic disks, the primary disk group identity on the disk is changed, and the disk is merged into the second computer's dynamic disk database. However, the primary disk group identity that is stored in the registry of the operating system on the disk is not changed. When you return the hard disk to the first computer, the mismatch between the new primary disk group identity and the primary disk group identity that is stored in the registry causes the error.

A "Stop 0x0000007B" error message occurs after you move the system disk to another computer

When you move the system (boot) disk of one Windows 2000-based computer to another computer, you may receive the following error message when you try to start the other computer:
***STOP: 0x0000007B (0xF741B84C,0xC0000034,0x00000000,0x00000000)
INACCESSIBLE_BOOT_DEVICE

Cause

This problem occurs if the computer that you moved the system disk to uses different hardware than the original Windows 2000-based computer. For example, this problem occurs if you move the system hard disk to a back up computer that is a different model that the original computer. In this situation, the registry entries and drivers for the mass storage controller hardware in the backup computer are not installed in Windows.

There are several different chipsets that are available for integrated device electronics (IDE) controllers, and each chipset uses a different Plug-n-Play (PNP) ID to identify it. The PNP-ID information of mass storage controllers for the backup computer must be in the registry so that Windows can initialize the correct drivers when you start the computer.

Resolution

The supported method of moving a Windows 2000 installation to new hardware is documented in the following article in the Microsoft Knowledge Base:
249694  (http://support.microsoft.com/kb/249694/ ) How to move a Windows 2000 installation to different hardware
However, for a disaster recovery method, do the following as appropriate for your situation:
  • Use the same hardware for the backup computer.
  • Replace the problem hardware components in the backup computer with the same manufacturer, make, and model as the components in the computer that you are backing up.
  • Use the same make and model of SCSI controller in the new computer, if the system disk is a SCSI disk.
  • If the system disk is an IDE disk, use the same type of motherboard that has the same type of IDE chipset, and the same PNP-ID as the original computer.
For SCSI-based system disks, you can prime the registry, and make sure that the drivers that you want are installed if you install the SCSI controller that is used by the backup computer before you transfer the system disk contents. Windows PNP detects the controller, sets up the critical registry entries, and then copies the appropriate driver.

After you verify that the SCSI controller appears in Device Manager, you can safely remove the alternate controller. If you have to move the system drive to another computer that has the same make and model of SCSI controller later, Windows can start successfully because it already used that controller one time and retains the correct configuration information.

Additional information

Although Microsoft does not support the following method, you can import or merge the required registry entries and copy the drivers ahead of time to support the IDE controllers that are natively supported by Windows. This method may enable system drives that you moved to start successfully. However, other hardware differences may result in other problems. This solution can provide support for IDE controllers whose PNP-ID matches the following list. However, if you want to determine ahead of time the IDE controllers that are used in your current and backup computers, you can search the %SystemRoot%\Setupapi.log file for the PNP-ID that is detected during Setup. After you determine the PNP-IDs that are used in your computers, you can choose to merge or to populate the registry with only the PNP-IDs that you need.

The following list is a list of the PNP-IDs of natively supported IDE controllers in Windows:

A "Stop: 0x0000007B" error message occurs when you start your computer to a mirrored dynamic disk

If you use software mirroring on dynamic disks for your boot partition, you may receive the following error message when you start and when you shutdown your computer:
STOP: 0x0000007B (0x817bdee8, 0xc0000010, 0x00000000, 0x00000000) Inaccessible_Boot_Device
Note The second parameter in the error message is defined as:
0xc0000010 STATUS_INVALID_DEVICE_REQUEST

Cause

This problem may occur in situations when the primary boot disk at some time reported some unrecoverable disk I/O errors, and has failed redundancy. This causes the primary boot volume to be flagged with a "recover" status in the Logical Disk Manager (LDM) database, and prevents booting to the stale volume.

Resolution

To work around this problem, use a fault tolerance (FT) boot floppy to restart the computer to the operating system that is located on the shadow drive.

After you restart your computer to the operating system on the shadow drive, start Disk Management, right-click the primary drive (it should have a yellow triangle displayed next to it that indicates that it needs attention), and then click Reactivate disk to remove the recover flag and start regeneration. After the mirror is regenerated and healthy, you can restart your computer as you do normally to the primary drive.

However, make sure that you investigate why the primary drive had I/O errors and to correct the problem to prevent the reoccurrence of this problem. Check the system event log for event messages that are logged by the Dmio event source before the startup problem.

Note If the unrecoverable disk I/O errors that caused this problem only occurred early in the boot process, the system event log may not contain any messages about the failed redundancy until after you successfully start your computer to the shadow drive.

When you use dynamic disk mirroring for the operating system disk before you restart the computer, look in Disk Management to make sure that the mirrored volume and dynamic disks are in a healthy state and do not show errors. If errors appear, take action to correct the error or errors by reactivating the disk to reset the LDM flags. If this action does not succeed, restart your computer to the shadow drive by using a fault tolerance (FT) boot floppy disk for the next scheduled restart.

A "Stop 0x0000007B" error message occurs when you start your computer after you install a new motherboard

When you start your computer after you install a new motherboard, you may receive the following error message on a blue screen:
STOP: 0x0000007B: (parameter1, parameter2, parameter3, parameter4)
INACCESSIBLE_BOOT_DEVICE

Cause

This problem may occur if the new motherboard contains an embedded IDE controller that uses a different chipset than the original motherboard.

Resolution

To resolve this problem, restart Windows 2000 Setup and then repair the Windows 2000 installation. To do so, follow these steps:
  1. Start your computer by using the Windows 2000 Setup floppy disks or from the Windows 2000 CD-ROM.

    Note To start your computer from the Windows 2000 CD-ROM, your computer must be configured to start from the CD-ROM drive or DVD drive. For more information about how to configure the computer to start from the CD-ROM drive or DVD drive, see the documentation that came with your personal computer or contact the manufacturer.
  2. At the Welcome to Setup screen, press ENTER.
  3. Read the license agreement, and then when you are prompted to accept the Windows 2000 licensing agreement, press F8.
  4. Select your current installation of Windows 2000 (if it is not already selected), and then press R.
  5. Follow the instructions that appear on the screen to repair your installation of Windows 2000.

You receive a "Stop 0x00000058 FTDISK_INTERNAL_ERROR" error message when you start your computer to a shadow drive from a broken basic mirror

With Windows 2000 you can upgrade a Microsoft Windows NT 4.0-based server where the operating system disk is software mirrored, without first having to break the mirror. Windows 2000 has certain restrictions that are associated with basic disks and earlier fault tolerant sets such as mirrors. One restriction is that you cannot boot from a "stale" or out-of-sync primary drive to the shadow drive.
If for any reason your primary operating system drive does not work or goes offline while it is in a software-mirrored configuration, Windows 2000 continues to run from the shadow drive. If you perform a typical shutdown at this point and revive the primary operating system drive, you cannot use the primary drive to boot back into the functioning shadow drive. This is apparent only if you already have an entry in the Boot.ini file that points to the shadow drive operating system, and then you try to use that entry after the primary drive does not pass redundancy. In this situation, you receive a "Stop 0x00000058 FTDISK_INTERNAL_ERROR" error message when you try to boot to either the primary or the shadow operating system disk. If you then remove or turn off the shadow drive and then try to boot into the stale primary drive, you receive a "Stop 0x0000007B INACCESSIBLE_BOOT_DEVICE" error message. This is also a protection mechanism because the most current data is on the shadow drive.

Note The information in this article only applies to basic disks, and does not apply to dynamic disks.
To guard against data loss and to fully recover from the "Stop 0x00000058 FTDISK_INTERNAL_ERROR" error message, follow these steps:
  1. Use a Windows NT fault tolerant boot floppy disk to start your computer to the shadow (secondary) system drive.
  2. In Windows 2000, follow these steps:
    1. Click Start, point to Settings, and then click Control Panel.
    2. Double-click Administrative Tools, and then double-click Computer Management.
    3. Double-click Storage, and then click Disk Management.
    4. Right-click the mirror partition, and then click Resynchronize Mirror.

      When the status of the mirror appears as Healthy, shutdown, and then restart your computer.
    5. Start your computer to the healthy primary operating system drive.
    Note Mirrored dynamic disk operating system drives do not have this restriction. In a similar situation, if you use mirrored dynamic disks, you do not receive the "Stop 0x00000058 FTDISK_INTERNAL_ERROR" error message when you start your computer to the shadow drive. This is one of the advantages that dynamic disks have over basic disks.

A "Stop 0x0000007B" error message occurs after you remove Roxio Easy CD Creator 5 Platinum

When you restart the computer after you remove Roxio Easy CD Creator 5 Platinum, you may receive a Stop error message on a blue screen that is similar to the following:
*** STOP: 0x0000007B (0xF741B84C, 0xC0000034, 0x00000000, 0x00000000)
INACCESSIBLE_BOOT_DEVICE
You may also receive this error message when you reinstall Roxio Easy CD Creator 5 Platinum edition.

Cause

This problem may occur if the PrtSeqRd.sys UpperFilters driver registry entry that was added by Easy CD Creator 5 Platinum Setup is not removed when you remove Easy CD Creator 5 Platinum. When you remove the program, the PrtSeqRd.sys driver file is removed, but the UpperFilters entry may remain in the registry. In this situation, you may receive a "Stop 0x0000007B" error message when you start Windows.

Resolution

To resolve this problem, use the following methods in the order that they appear. Try the next method only if the previous method does not resolve this problem.

Cause

This may occur if certain registry entries that are added by Veritas Open Transaction Manager when you install the program are not removed when you remove the program, and these registry entries are preventing your computer from starting correctly.

Resolution

To resolve this , manually remove the remaining references to the Otman5 driver from the registry. To do so, you first have to install a parallel copy of Windows 2000 to a separate folder, and then use Registry Editor to modify the System hive in the registry. To do so, follow these steps:
  1. Perform a parallel installation of Windows.

    For more information about how to do so, click the following article number to view the article in the Microsoft Knowledge Base:
    266465  (http://support.microsoft.com/kb/266465/ ) How to perform a parallel installation of Windows 2000 or Windows Server 2003
  2. In the new installation of Windows, click Start, and then click Run.

    In the Open box, type regedit, and then click OK.
  3. Locate, and then click the HKEY_LOCAL_MACHINE key.
  4. On the Registry menu, click Load Hive.
  5. Locate the %SystemRoot%\System32\Config folder of the original Windows installation, click the System file, and then click Open.
  6. In the Load Hive box, type test, and then click OK.

    The System hive of the original Windows installation is loaded under the current HKEY_LOCAL_MACHINE hive as test.
  7. Locate, and then click the following registry key:
    HKEY_LOCAL_MACHINE\Test\Select
    Make a note of the value of the Default entry.

    For example, the value may be 0x1.
  8. Locate, and then click the following registry key, where x is the number that you determined earlier in step 7:
    ControlSet00x\Control\Class\{4D36E967-E325-11CE-BFC1-08002BE10318}
  9. In the right pane, double-click the UpperFilters value, and then remove the Otman5 line.
  10. Locate, and then click the following registry key, where x is the number that you determined earlier in step 7:
    ControlSet00x\Control\Class\{71A27CDD-812A-11D0-BEC7-08002BE2092F}
  11. In the right pane, double-click the UpperFilters value, and then remove the Otman5 line.
  12. Unload the test registry subkey. To do so, follow these steps:
    1. Click test, and then on the Registry menu, click Unload Hive.
    2. Click Yes to confirm the unloading of the test key and all its subkeys.
