As you know, storage devices are an important part of the computer system for porting, saving, and extracting data files. And for you to differentiate between storage devices on your computer system, each one of the storage devices is labeled with a unique number referred to as Disk Signature for identification. The unique disk identifier is stored as a part of the MBR or Master Boot Record. Disk signature is used by operating systems in order to identify and set apart different data storage devices and hard disk drives in the computer for data access. These days, Disk cloning has become a regular practice in upgrading to larger hard disk drives. Drives are cloned in order to produce a similar copy to use both the original drive and cloned copy together. Moreover, lots of virtualization tools are being used to virtualize the physical hard disk drives to create virtual hard disk drives and several virtual machine clones that are created with the existing virtual hard disk drives. And since these are identical copies, chances these copies may have identical disk signatures. As a result, when you use both disks that have identical signatures at the same time you run into the Disk Signature Collision problem. This kind of problem does not often occur as the Windows system does not really allow two disks to function simultaneously when they have the same disk signature. When you encounter a Disk Collision problem in your Windows 10 computer, you may see the following error messages:

• The boot selection failed because a required device is inaccessible
• The disk is offline because it has a signature collision
• This disk is offline because it has a signature collision with another disk that is online

You can fix the disk collision problem by changing the disk signature which you can achieve using the command line utility diskpart in Windows PowerShell or Command Prompt or using Windows Disk Management utility. To fix the disk collision problem, you can make use of the command-line utility called diskpart in Windows PowerShell or Command Prompt to view and change the signature, or can make use of Master Boot record in the Windows Registry. You can also make use of Windows Disk Management Utility to change the signature. Simply follow the given options below to change the disk signature either way.

Option 1 – Change Disk Signature via Diskpart

• Type “command prompt” in the Windows Search bar and then right-click on the related search result and select the “Run as administrator” option.
• After that, type the “diskpart” command and hit Enter to open Diskpart.
• Next, type the “list disk” command to display all the disks available in the system.
• Next, take note of the problematic disk number with the status Offline from the list and then type the “Select disk x” command where x is the offline disk to select the offline disk. For instance, if you type “select disk 1”, it will display the “Disk 1 is now the selected disk” message.
• Now type the “Uniqueid disk” command to display the disk signature and to change the disk’s signature and set the disk online, type the “unique disk ID= (New signature)” where (New signature) is the new ID in hexadecimal. For instance, you can set the new id as “unique disk ID= 1456ACBD”.

Note: If you have given the wrong format ID, the command prompt will display the following error:

“The specified identifier is not in the correct format. Type the identifier in the correct format: in hexadecimal form for an MBR disk or as a GUID for a GPT disk.”

• After you’re done, the disk will be online, and then restart your computer.

Option 2 – Change Disk Signature via Disk Management Utility

• Tap the Win + R keys to open the Run dialog box and then type “diskmgmt.msc” and hit Enter or click OK to open Disk Management.
• Next, right-click on the disk that is marked as Missing or Offline.
• After that, select the Online command from the drop-down menu.
• Then from the selecting option Online, Windows will generate a new disk signature.

Error Code 0x8007267C – What is it?

Error code 0x8007267C is specific to Windows 10. This error is triggered when no DNS server is currently configured in your network settings during the Activation process. If you are fairly confident in your ability to address command-line tools and networking issues, you can follow the steps below to try to remedy the error code on your own. If not, you may need to contact a qualified technician in order to resolve the error successfully.

Solution

Error Causes

The cause of Error Code 0X8007267C within the Window 10 system is fairly straightforward. Windows Activation requires a valid DNS server to be configured in order to complete the Activation process; if one is not available or properly configured, then you may see this error code and Activation will fail.

Further Information and Manual Repair

The following methods may help you to resolve this error, but you’ll need to have some familiarity with command-line tools to complete the steps successfully. If these methods do not work or if you are uncomfortable in using the command prompt, you may need to consult a technician to fully resolve this particular error code on the Windows 10 system.

Method 1: Register a DNS server within your network properties and test the connection.

In order to resolve this error code, client connectivity to a DNS server must first be established. The following steps may help you to determine the root problem with your connectivity status:

1. Open a command prompt, after which you'll run IPCONFIG /all
2. Verify the following values: The IP address that has been assigned, the DNS server, the subnet mask, and the default gateway. Compare each to ensure that all are set with the values that correspond to your specific environment
3. Check for basic IP connectivity to the DNS server using the PING command. In using the PING command, utilize the address of the DNS server found in Step 1

ping <DNS Server IP address>

If basic connectivity to the DNS server in question is failing, then you will need to resolve that issue before going further in the process.

After troubleshooting the above basic connectivity issues to the DNS server, you can reattempt Windows Activation by using the command below from within an Elevated Command selection:

cscript windowssystem32slmgr.vbs -ato

If the steps above did not work for you, you may want to try the steps found in method 2.

Method 2: Use phone-based authentication with a MAK (multiple activation key).

If a DNS server is not connected to your network, you can use an alternative method to complete the Windows Activation process. Bypass Method 1 by using a MAK product key instead to activate the volume license installation. Certain MAK product key providers have a variation on the specific key numbers that you will need to use. If you are using TechNet media or MSDN media, you will have to change the product key listed to the product key provided. The product keys provided by either TechNet media or MSDN media for Windows Server 2008 or for Windows Vista Enterprise will be the MAK product key that you will enter in a later step.

Like the previous method, you will need to have some familiarity or confidence in your ability to operate Command Line tools before proceeding. Once you have found your MAK product key, you’ll need to open a command prompt and use the following command to change the product key to match the MAK product key, which should look something like the example below:

            slmgr –ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx

After completing the product key change, use the following command to initiate the phone activation wizard, thereby completing the activation of the system:

            slui 04

The activation wizard should be able to walk you through the remainder of the process in a step-by-step manner. In addition to appearing as an error code in Windows 10, this particular error may apply to multiple versions of Windows, including:

• Windows 7 Enterprise
• Windows 7 Enterprise E
• Windows 7 Enterprise N
• Windows 7 Professional
• Windows 7 Professional E
• Windows 7 Professional N

Steps to address the error code may be different in any of these other versions of Windows. If you have difficulty in resolving the error effectively, seek professional technical help.
