The OS disk size is determined by the marketplace image that you are using. Generally marketplace Windows images are 127/128GB and Linux are 30/32GB, there are some Windows "smalldisk" options with 32GB and 64GB options available. You cannot change the OS disk size at creation time, it will create an OS disk size that matches the image that was used.

You would need your disk image to be 64GB. Otherwise, you would have to deploy the VM first and then resize the OS disk after deployment.
