JSI Tip 7192. When you start Windows 2000, you receive 'STOP: 0x0000007b - Inaccessible_Boot_Device'?

When you start Windows 2000 after reinstalling your system disk, which had temporarily been attached to a second Windows 2000 computer, you receive:

STOP: 0x0000007b (0xf881b84c,0xc0000034,0x00000000,0x00000000)

This STOP will occur if the primary disk group identity of the disk does NOT match the value stored in the registry.

If the system partition is a dynamic disk, when you imported the disk on the second computer that had dynamic disks, the primary disk group identity was changed, as Windows 2000 only supports one dynamic disk group. Since the broken computer's registry was NOT active, it wasn't changed.

To fix this problem:

01. Reinstall the disk in the second computer.

02. Use Regedt32.exe to select the HKEY_LOCAL_MACHINE Hive.

03. On the Registry menu, press Load Hive.

04. Navigate to the System file on the broken install, X:\Winnt\System32\Config\System, where X represents the drive letter of your broken computer's system partition on the second computer.

05. Press Open and type AFIX into the Key Name box.

06. Press OK.

07. Navigate to HKEY_LOCAL_MACHINE\AFIX\ControlSet00n\Services\dmio\Boot Info, where n is a control set number.

08. Right-click Primary Disk Group and press Delete.

09. If prompted. confirm the deletion.

10. Repeat steps 07 through 09 for each control set (n).

11. Select the AFIX key.

12. On the Registry menu, press Unload Hive.

13. Press Yes to confirm.

14. Close Regedt32.exe.

15. Shutdown the second computer and remove the broken computer's hard disk.

16. Install the disk in the broken computer.

17. Start the now fixed computer normally.
