If you already have an existing VM or disk it shouldn't be necessary to first create a VHD. There are other methods to create an image from an Azure VM or a managed disk. Some of the methods are:

Using the Azure portal, you can capture an image from a VM by selecting Capture on the upper menu of the Virtual machine page

Using Azure Compute Gallery, you can create an image definition and image version for your VM or disk3.

Is there a reason you are following this method? If so could you provide some more details of the VM/disk you are trying to create an image of?

Normally the VHD process is used when first importing a VM into Zzure. This problem occurs for one of the following reasons:

• The VHD does not comply with the 1 MB alignment (offset). The supported disk size should be 1 MB * N. For example, the disk should be 102,401 MB.
• The VHD is corrupted or not supported.

To resolve this problem, resize the disk to comply with 1 MB alignment:

• To resolve the problem in Windows, use the Resize-VHD PowerShell cmdlet. Note that Resize-VHD is not an Azure PowerShell cmdlet.
  1. Install the Hyper-V role on Windows Server
  2. Convert the virtual disk to a fixed size VHD
• To resolve the problem in Linux, use the qemu-img command.

Hope this resolves your issue. Let me know if you still need assistance and I will be happy to help.
