Scenario: An employee attempts to log in to a Desktop OS machine and receives the following error: Startup Failed Personal vDisk failed to start Status Code: 15 How could a Citrix Administrator…

Changing the VM startup order affects the sequence in which virtual hardware and services initialize, but does not resolve an inventory synchronization failure reported by Personal vDisk.

Restarting the Desktop OS machine does not clear an inventory mismatch; the Status Code 15 error will recur on the next boot because the underlying inventory data remains out of sync.

Status Code 15 is a specific Personal vDisk error that means the vDisk inventory is out of sync with the current state of the base image - for example, after applications have been installed or updated on the image without a corresponding inventory update. Running an inventory update re-scans the master image and reconciles the vDisk inventory, allowing the Personal vDisk to start successfully.

Reconfiguring the Virtual Delivery Agent addresses VDA registration and communication issues with the Delivery Controller, which is unrelated to a Personal vDisk inventory failure.
