Add Lenovo diagnostics and BIOS Updates to E2B

The linux bootable Lenovo Diagnostics ISOs can simply be copied to any E2B menu folder (e.g. \_ISO\UTILITIES). The diagnostics will only run on Lenovo-branded systems.

The linux-bootable-cd-41308857.iso is also UEFI 64-bit bootable.

Install the E2B MPI Tool Kit and then drag-and-drop the ISO onto the Windows MPI_FAT32 shortcut (I suggest you rename the ISO first because the CSM menu title has the same name as the ISO file).

Lenovo also supply UEFI-bootable versions of their diagnostics.

Make a Lenovo UEFI diagnostics .imgPTN file

1. Download the 32-bit and the 64-bit UEFI Diagnostics .zip files from here.

2. For each one, extract and combine the EFI folders to the same new empty folder,

e.g. two files in the same folder:


3. Drag-and-drop the Lenovo_UEFI_Diag folder onto the Windows Desktop MPI_FAT32 shortcut and create a new .imgPTN file (e.g. C:\Temp\Lenovo_EUFI_Diagnostics.imgPTN).

4. Finally, copy the .imgPTN file to your E2B USB drive (e.g. \_ISO\UTILITIES\Lenovo_UEFI_Diagnostics.imgPTN) and run \MAKE_THIS_DRIVE_CONTIGUOUS (run as admin).cmd from the E2B drive to ensure the file is contiguous.

Note that this image file is not capable of booting via MBR to the Lenovo diagnostics.

Combined Lenovo MBR+UEFI .imgPTN file

1. Drag-and-drop the linux-bootable-cd-41308857.iso onto the Windows MPI_FAT32 shortcut (I suggest you rename the ISO because the CSM menu title will have the same name as the ISO), e.g. name it Lenovo Diagnostics (

2. Switch to the new .imgPTN file - e.g. Lenovo Diagnostics (

3. Download the 32-bit UEFI diagnostic zip file (see above) and add the BOOTIA32.EFI file to the \EFI\BOOT folder.

Lenovo UEFI-only BIOS update ISOs

For use with UEFI BIOS ISO updates, e.g. this type.

Note: The extracted files must contain a \EFI\BOOT\BOOTX64.EFI file or it will not UEFI-boot.

Follow these steps:

  1. Download and install IsoBuster onto your Windows system
  2. Use IsoBuster to extract the large .img file from the ISO (see screenshot above)
    IMPORTANT: There must be a \EFI\BOOT\ folder present inside the .img file. If not, then try another tool to extract the files - e.g. PowerISO (see below).
  3. Drag-and-drop the .img file onto the MPI_FAT32 desktop shortcut
  4. Copy the .imgPTN file to your E2B USB drive
  6. Select the .imgPTN file (MBR boot or use SWITCH_E2B.exe)
  7. You can now UEFI-boot from the E2B USB drive to run the BIOS update
Tip: Add agFM to your E2B drive and rename the file to .imgPTN23. Then you can UEFI-boot directly from the E2B drive and pick any .imgPTN23 file you like.

P.S. Can also use PowerISO - Action - Extract...
