Windows failed to start. Status: 0xc0000225



This article explains the cause and solution when a Windows virtual machine fails to start with the error code: 0xc0000225.


This error code is commonly seen when the host machine has difficulty with the Advanced Configuration and Power Interface (ACPI).

  • The machine is having difficulty with the virtualization storage controller driver.
  • While rare to encounter, it is possible that the Virtual Box setting which enables ACPI was unchecked.


Change the virtualization storage controller from Datto appliance GUI, and attempt virtualization again. See Agent Configuration - Virtualization Options for more information.
