For the recovery, you must use the 32- or 64-bit integrated BMR ISO image provided on the Unitrends Recovery-Series or UEB appliance. The ISO contains WinPE 4.0, a minimal version of Windows used for installations, and the Unitrends Integrated Bare Metal Recovery Wizard that guides you through the recovery. For details about WinPE 4.0, see WinPE: Windows PE Overview. To access the images, see Accessing the integrated bare metal recovery ISO images.
