This article provides information about making an USB device bootable and integrating an update-image (ISO-file). For servers without an optical drive (DVD) or a configured integrated Dell Remote Access Controller (iDRAC) this is an alternative way of updating all server firmwares in one single step.
To create a bootable USB device, you can use the freeware tool Rufus (Figure 1).
Note: Rufus is not a Dell certified software. Installation and use on own risk. We share our best practices with Rufus but do not support issues regarding this program.
  1. Download the tool to a Windows system
  2. Create a Smart Bootable ISO using the Dell Repository Manager (DRM).
  3. Start the tool
  4. Insert a USB device  (Rufus will auto-select if USB device)
  5. Choose the created or downloaded ISO-file  (Rufus will select the appropriate settings)
    • Partition Screen = MBR
    • File System = FAT32
    • Cluster Size = 1024
  6. Click on Start to create the media
  7. Restart the server and boot from the created device

SLN296810_en_US__1icon If the Bootable ISO fails to run after being applied to a Bootable usb please change the server boot mode to BIOS or UEFI mode and attempt the procedure again. If the Bootable ISO continues to fail, it is recommended to download the iso again or try applying the image to a different USB key.
