A couple of weeks ago, I blogged about boot diagnostics and how they can help you troubleshoot issues when virtual machines won’t start. But what if you selected to disabled boot diagnostics when the virtual machine was created? Can you go back and retro-actively add them back?
Yes, Virginia, yes you can. There is indeed a Santa Clause. It’s pretty simple to do.
Open the Azure portal, locate the virtual machine in question, and go to Boot Diagnostics.
