There are occasions where you must create a bootable USB Flash Drive. Scenarios that require a USB drive include a BIOS update outside the operating system, when no operating system is installed, or when the computer cannot boot to the operating system. Difficulty getting the BIOS updates to work within the Operating System, due to permissions, restrictions, anti-virus, or compatibility with the update schedule.

By default, most USB flash drives are not bootable, and computers do not recognize them during the boot process.

There are several different ways to create a bootable USB flash drive. One way is to use the DDDP.

Note: Using DDDP only creates a bootable partition of up to 2 GB in size, on the USB flash drive. If you require a larger bootable USB flash drive, learn How to Make a Bootable USB flash drive Using Diskpart.

  1. Download the Dell Diagnostic Distribution Package (DDDP), go to
    1. The File Download window is displayed. Select Run to download the software.
