@HASSAN BIN NASIR DAR Welcome to Microsoft Q&A Forum, Thank you for posting your query here!

Adding more information to above response

Let me explain why you need OS disk and what's been used for: Every virtual machine has one attached operating system disk. That OS disk has a pre-installed OS, which was selected when the VM was created. This disk contains the boot volume. This disk has a maximum capacity of 4,095 GiB.

Without VM creation we can't create OS disk , Using OS disk you can create a New VM

There are three main disk roles in Azure: the data disk, the OS disk, and the temporary disk. These roles map to disks that are attached to your virtual machine.
For more information on Azure disk, please refer here: https://learn.microsoft.com/en-us/azure/virtual-machines/managed-disks-overview

Answer 2

Hi @HASSAN BIN NASIR DAR ,

the easiest way to get a OS disk without a VM is to create a VM with OS disk and delete the VM after deployment.
If an Azure VM will be deleted the OS disk will not be deleted automatically.

It's possible to upload a vhd-file of an on-premises OS disk as well:

With some more details regarding your use case there might be more options.
