Let me know what PERC controller you have (H330, H740P, etc.) if the issue persists. Use this in WinPE as a replacement for raw ZTIDiskPart:
Dell PowerEdge (Rx40, Rx50, Rx60), Dell Precision Workstations, Windows Deployment Services (WDS), Microsoft Deployment Toolkit (MDT).
Hi there – this is a common Dell deployment issue. ZTIDiskPart is failing because Disk 0 has a protected partition, old RAID config, or is offline.
