10.2.8 Creating a Bootable USB Memory Stick (Optional)
These instructions enable you to create a bootable USB memory stick that can be used for
updating Nucleus2 controllers.
1. Format the USB memory stick from Microsoft Windows Explorer using the Quick
Format option and selecting the FAT file system (not FAT 32 or NTFS).
2. Now use Pbak Deploy in the normal way (see section 10.2.1).
3. If the Nucleus2 controller fails to boot from the USB memory stick you will need to
format another USB memory stick or use the advanced formatting option detailed in
Section 10.2.8.1
10.2.8.1 If the USB Memory Stick Doesn’t Work
This process is for advanced Microsoft Windows users only and should only be carried out if
the process in Section 10.2.8 fails to create a working USB memory stick for the Nucleus
controller.
If this process is carried out incorrectly you could potentially format the wrong disk drive which
would lead to data loss and possibly make your computer unusable. If you are unsure then it
is best not to proceed.
1. Plug a USB memory stick into the computer.
2. Open the command prompt by clicking the Start button and typing “cmd” into the
Search box. Select cmd.exe from the results window and the command window will
open.
3. Type “diskpart” followed by the Return key.
If a UAC (User Access Control) message is displayed click on Yes to proceed.
4. The Diskpart> prompt will be displayed.
5. At the Diskpart> prompt type “list disk” followed by the Return key to display the disks
available on the PC. For an example see Fig 78.
