VHD_BOOT_INITIALIZATION_FAILED
VHD_BOOT_INITIALIZATION_FAILED reports a failure while Windows is preparing a virtual hard disk as the boot device. Parameter 1 identifies the failed initialization action and parameter 2 carries the associated NTSTATUS.
The action code distinguishes failure to extract VHD boot information, timeout waiting for the parent device, path allocation or construction failure, VHD mount failure, sleep-state configuration failure, and VHD-information allocation or construction failure. Record both values before recovery changes the boot environment.
VHD_BOOT_INITIALIZATION_FAILED Parameters
| Parameter | Description |
|---|---|
| 1 | Action that failed 1 : Couldn't extract VHD information from boot device. 2 : Timeout waiting for VHD parent device to surface. 3 : VHD path string memory allocation error. 4 : VHD path construction failed. 5 : VHD boot device mount failed. 6 : Disable sleep states failed. 7 : VHD information memory allocation error. 8 : VHD information construction failed. |
| 2 | NT status code |
| 3 | Reserved |
| 4 | Reserved |
Diagnostic focus
Interpret the action code first and then decode parameter 2 for the lower-level cause. Verification should repeat the same VHD boot path and confirm that the parent device, path construction, mount, and information setup reach the stage that previously failed.
