You use the Wbadmin.exe command-line tool to recover an Extensible Firmware Interface (EFI) volume on a Windows Server 2008-based computer. However, you receive the following error message:
ERROR - Online recovery of EFI System Partition is not supported. Please try recovering from Windows Recovery Environment.
This issue occurs because recovery of an EFI volume either as a volume or as a file is not supported in an online operating system (OS). However, recovery of an EFI volume either as a volume or as a file is supported in an offline Windows Recovery Environment (WinRE) by using the volume recovery command.
