Hi @Vijayanand Kottukal Vinodan ,

an Azure VM can't exist without an OS Disk.
There is no option to boot from any ISO/DVD/CD or USB Stick/Drive.

But you could create a "custom-defined VM Image" if this helps with your requirements:
https://learn.microsoft.com/en-us/azure/virtual-machines/windows/tutorial-custom-images
https://learn.microsoft.com/en-us/azure/virtual-machines/linux/imaging
https://learn.microsoft.com/en-us/azure/lab-services/how-to-bring-custom-linux-image-azure-vm

The link you provided in your question is an option as well.
