Hyper-V VM not recognising F8 Safe Boot Mode Keystroke

The Scenario

I have a Windows Server Vm running in Hyper-V. I have a problem with the OS and need to boot into Safe Mode by pressing F8 at boot time.

The Problem

The VM is not responding to the F8 keystroke, even if i start pressing it repeatedly, even over-zealously (mimicking days of yore when I played Daley Thompson’s Decathlon on the ZX Spectrum) as soon as the VM starts. The Safe Mode menu fails to materialise, instead it just boots as normal.

The Solution

Change the VM Automatic Start Action settings by changing the Automatic start delay time from 0 to 5 seconds (or any number great than 3 seems to work). Click OK to Confirm.

Now when you restart the VM and press F8 the menu will appear:
