  4. On your Windows Command-line application, go to the location you saved the BIOS update (that is cd c:\temp\) and type the following command to extract the recovery file:

    C:\<downloaded BIOS file location>\<downloaded BIOS filename.exe> /writehdrfile /writeromfile
  5. Rename the file from downloaded BIOS filename.hdr to BIOS_IMG.rcv.

  6. Copy the recovery image file BIOS_IMG.rcv to the root directory of a bootable USB drive.
