The Integrated BMR Wizard uses WinPe 4.0 for the recovery. WinPE 4.0 is based on Windows 8, and if it cannot detect a network adapter or storage disks, you must load Windows 8 drivers into WinPE for the restore.
Note: WinPe 4.0 is used only for the restore. After the wizard restores the critical volumes from the failed client, you might need to inject additional drivers into the restored operating system before you can reboot the restored client.
