As you use your computer, install and uninstall programs, invalid registry entries accumulate. This slows down your computer and even causes blue screen crashes like 0x0000007B. If you install new programs over old ones without proper deletion that makes the situation even worse. You should either manually remove invalid entries from the registry or use specialized software for this.

STOP: 0x0000007B During Windows XP Setup or Startup (General Case)

One of the most general instances of STOP: 0x0000007B is when you cannot complete the setup process: Windows setup restarts with the STOP: 0x0000007B message. This sort of trouble may be caused by one of the following factors:

  • Boot sector viruses
  • Corrupted Windows XP registry entries responsible for loading device drivers during startup (miniport driver issue)
  • Corrupted miniport driver
  • Not properly configured boot controller driver

If the 0x0000007B failure is sporadic and you are able to startup in Safe Mode, you should scan you computer for viruses and repair the registry (or restore a hive from a registry backup, if you have one). 0x0000007B issue may be resolved at this stage. The case that the virus is detected but cannot be removed is the worst one: you’ll have to format your hard disk and reinstall Windows. If 0x0000007B remains, it can be because of absent or corrupted miniport drivers used to connect the OS with the hard disk controller during startup. For example, the driver was not included in Windows installation pack you are currently using. Start the installation again and during the 1st phase you’ll read the following: Press F6 if you have to install a third-party SCSI or RAID driver. After pressing F6 follow the instruction on the screen to install mass-storage device drivers
provided by your hardware manufacturer.

STOP: 0x0000007B After Moving Windows XP Disk to Another PC

You may get STOP: 0x0000007B when you try to start Windows XP based machine after installing the boot disk Windows XP from another computer.

In this case STOP: 0x0000007B occurs because Windows XP lacks the drivers and registry entries for the mass storage controller hardware in the new computer.

Technical Info

For integrated device electronics (IDE) controllers, there are several different chip sets available, such as Intel, VIA, and Promise. Each chip set has a different Plug-n-Play identifier (PnP-ID).

The PnP-ID information of mass storage controllers for the backup computer must be in the registry before startup so that Windows XP can initialize the correct drivers.

0x0000007B Solutions

There are 2 general methods of resolving this 0x0000007B instance.

  1. The most general advice is to use the same hardware for the second computer as for the one you moved the Windows XP disk from.

Ideally, you should replace hardware parts of the second computer by the parts of same make and model as the motherboard in the first computer, which is hardly possible. That’s is why:

For IDE disk computers: the second computer will need the same kind of motherboard as the first one, with same kind of PnP-ID and IDE chip set and, to be more specific. For SCSI disk computers: the new computer needs SCSI controller with of same make and model as the fist computer. Alternatively, you can prime the registry and install the SCSI controller used by the second computer. Windows XP PnP will see the controller, add important registry entries, and copy the required driver. You have to make sure the drivers are properly installed prior to moving the disk. Enter Device Manager to see if SCSI controller is detected. Only after that you can remove the alternate controller and move the disk to the second computer. After such manipulations STOP: 0x0000007B should be gone.

From this point on, moving this boot disk to a PC with the same make and model of SCSI controller will not cause 0x0000007B anymore because now Windows XP has the configuration corresponding to the new hardware.

  1. Add critical IDE controller related entries to the registry and copying the required IDE controller drivers to the

system prior to moving the disk. You may be able to start up without STOP: 0x0000007B after that, but other hardware incompatibility conflicts may occur in future.

STOP 0x0000007B When Changing the SATA Mode of the Boot Drive (Vista, XP)

0x0000007B may occur when you start up after changing the Serial Advanced Technology Attachment (SATA) mode of the boot disk in BIOS for AHCI or RAID specification.

You can fix 0x0000007B manually by enabling the AHCI driver in the registry prior to changing the SATA mode of the boot drive. Use the following directions:

  • Close all Windows applications.
  • Open Start menu and open Registry Editor by typing regedit in the Search box and pressing ENTER.
  • Find the following subkeys (in the same way as you browse folders in Windows Explorer):

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\IastorV HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci

  • Open these keys (to display the contents in the right pane of the editor)
  • Right-click Start in the Name column of the right pane, then choose Modify option.
  • Type 0 in the Value data box and click OK.
  • Exit Registry Editor by choosing Exit on the File menu.
