| Description | Hyper-V launch aborted due to auto-launch being disabled in the registry. |
| Event Information | According to Microsoft : Cause This event is logged when Hyper-V launch aborted due to auto-launch being disabled in the registry. Resolution Check BCD autolaunch Check that Boot Configuration Data (BCD) store is set to launch the hypervisor, and then restart your physical computer. The BCD store contains boot configuration parameters and controls how the operating system is started in Windows Vista and Windows Server 2008 operating systems. These parameters were previously in the Boot.ini file (in BIOS-based operating systems) or in the nonvolatile RAM (NVRAM) entries (in Extensible Firmware Interface-based operating systems). You can use the Bcdedit.exe command-line tool to update BCD store with the correct launch options as referenced in the error, and then restart the server. Bcdedit.exe is located in the \Windows\System32 directory by default. On PC/AT BIOS systems, the BCD store resides in the active partition's \boot folder. On EFI systems, the file is located on the EFI system partition (ESP) under \EFI\Microsoft\Boot. Verify Hypervisor successfully starts. |
