Manually Create a Bootable UEFI 64-bit USB Flash Drive (Windows 7, 8, 2008, 2012)

  1. Create bootable USB:
    • Open CMD (with runas administrator), and use the following command to create bootable USB:
      • diskpart
      • list disk  (to verify which disk is the USB)
      • select disk # (select the USB disk)
      • clean
      • create partition primary
      • format fs=fat32 quick
      • active
      • assign
      • exit
    • Copy all file from Installation CD/DVD to the USB. It should be already bootable for 32-bit.
  2. Make UEFI (64 bit) bootable:
    • On the USB flash drive, “copy” the efi\microsoft\boot folder up one level into the efi folder as efi\boot.
    • Use 7-zip to Open sources\install.wim on the USB flash drive,
      • Go to: \1\Windows\Boot\EFI\bootmgfw.efi
      • Copy bootmgfw.efi to somewhere (e.g. desktop), then close 7-zip
      • Rename the bootmgfw.efi into bootx64.efi.
      • Copy/Move the renamed bootx64.efi file into the efi/boot folder on the USB flash drive
