Consider the following scenario:
- You have a computer that is running Windows Server 2008 R2 or Windows 7.
- You configure the computer to start from an iSCSI disk or PCI Express NIC.
- The computer supports PCI Express Serial Number Capability.
- You replace the iSCSI or PCI Express network adapter or the motherboard on the computer with an identical device. For example, you replace the device because of a hardware failure.
- You log on to the computer, and then you restart the computer.
STOP 0x0000007B (parameter1, parameter2, parameter3, parameter4) INACCESSIBLE_BOOT_DEVICE
Notes- The four parameters in this Stop error message may vary, depending on the configuration of the computer.
- Not all "0x0000007B" Stop error messages are caused by this problem.
- A similar problem occurs on Windows Server 2008-based or Windows Vista-based computers. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
2487376 FIX: Stop error when you replace an iSCSI network adapter or a motherboard with an identical device on a Windows Server 2008-based or Windows Vista-based computer: "0x0000007B" - Note the replacement network adapter must be placed in the same slot as the original network adapter.
- After applying this hotfix, even when you replace the device with the PCI Express device holding a different serial number, the device instance path would not be modified as long as the same device model is connected to the same slot. In this case, the same device instance path, which is stored in the registry, would continue to be used. Thus, the reinstallation of the device does not occur.
- Note that if the failed iSCSI network adapter is a built-in device, and you choose to use a different built-in adapter for iSCSI boot, that installing this hotfix will not resolve the issue, because the adapter would not be in the same PCI-Express location. You would need to manually unbind the Light Weight Filter (LWF) from the second network adapter. See the following KBs for more details: KB2507616, KB976042
