Part 3: Prerequisites – What You Will Need

Before creating your bootable USB, gather the following: hp dmi tool bootable usb

Step 2: Write the System Serial Number

The format is:

DMI236A /SV [YourSerialNumber]

Example:

DMI236A /SV CND1234ABC

Serial numbers are usually 10–12 alphanumeric characters located on the bottom sticker of the laptop.

Creating the EFI Shell USB:

  1. Format USB to FAT32 on any PC.
  2. Create a folder on the USB: EFI\BOOT\
  3. Download Shell.efi (renamed to BOOTX64.EFI) and place it in EFI\BOOT\.
  4. Copy DMI500.efi or DMI.EFI (from HP SoftPaq) to the USB root.
  5. Boot the HP laptop, press F9, choose Boot from EFI File → navigate to DMI500.efi.

In the EFI shell, you run:

fs0:
DMI500.efi /SV "CND1234ABC"
DMI500.efi /SP "6FU84AV"
exit

5.1 Boot the Target HP System

  1. Insert the USB drive into the HP system.
  2. Power on and press F9 (Boot Menu) repeatedly.
  3. Select Boot from EFI File → select your USB drive → choose EFI\BOOT\BOOTX64.EFI.
  4. The UEFI Shell launches. You will see a Shell> prompt.

Step 5: Create an Automatic Startup Script (Optional but Highly Recommended)

In the USB root, create a text file named STARTUP.NSH. Add these lines:

echo -off
cls
echo HP DMI Tool Bootable USB - UEFI Mode
echo.
echo Attempting to load DMI tool...
fs0:
cd EFI\HP
HPDMI64.EFI

Save as plain text, not rich text.

If your DMI tool is called NBDMI64.EFI, adjust the last line accordingly.
