Windows Azure: Delete disk attached to non-existent VM
If I am understanding correct, Once you delete a Virtual Machine, it delete the service but keep a copy of the VHD image under Disks. So please go to the Disks tab under virtual Machine and try to delete it.
If that is not the case, please add a screenshot with error message from where your trying to delete VM.
The only way to do this that I can see is through PowerShell. I ran into the same problem and here's how I fixed it. I installed the Azure PowerShell extensions and configured my subscription and then my storage account. Once I did that I then ran this command
get-azuredisk | Remove-AzureDiskGet-azuredisk will grab all disks In my case I needed all of them removed. If you need to do individual then you need to get the name of the disk and then run remove-azuredisk with the name switch and specify the disk name to remove it. That fixed it for me. Hope this helps someone in the future.
In the "new" Azure portal. Select Storage Accounts, then click on the storage account" where your none used VHD's are located, Click Blobs under Services, Click vhds under Essentials, search for unwanted vhd and click delete.
