is it possible to boot an Azure VM with a different bootable iso?

Question

just for a hypothetical case: is it possible to boot a VM in Azure with an ISO file and a different OS? Eg. I have a Windows Server 2016 and want to boot this VM with a Linux?

For instance if the MBR is destroyed or other issues that block the VM from booting and i might be able to fix this with a Linux.

Unfortunately, for now Azure does not support this.

If our windows OS MBR is destroyed or other issues that block the VM from booting, to fix this problem, we should download this VM's VHD to local, and use Hyper-V to fix it with ISO file. After completed, we should upload this new VHD to Azure storage account, and use this new VHD to create Azure VM(create it with existing Vnet and public IP address, just replace this VHD).
