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 Dell Diagnostic Deployment Package (DDDP).
You can create a bootable USB flash drive using the following instructions:
- Download the Dell Diagnostic Distribution Package (DDDP), go to https://downloads.dell.com/diags/CW1322A1.exe.
- The File Download window is displayed. Select Run to download the software.
- A User Account Control (UAC) window may appear. Select Yes to continue the download process.
- The Dell 32-bit diagnostic window appears. Select Continue to progress.
- The folder creation window appears. Select Ok to use the default folder.
- A Dell Diagnostic dialog window appears stating all files were successfully extracted. Select Ok to continue. The DDDP main menu appears. Close the window by clicking the X on the upper right corner.
- Browse to the folder where DDDP was extracted to (the default location is
C:\Dell\Drivers\R174621) and select the DIAGS folder (Figure 1).
