This article provides information about making a 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 firmware 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 it at your own risk. We share our best practices with Rufus but do not support issues regarding this program.
- Download the tool
to a Windows system
- Create a Smart Bootable ISO using the Dell Repository Manager (DRM).
- Start the tool
- Insert a USB device (Rufus auto-selects the USB device)
- Choose the created or downloaded ISO-file (Rufus selects the appropriate settings)
- Partition Screen = MBR
- File System = FAT32
- Cluster Size = 1024
- Click Start to create the media
- Restart the server and boot from the created device
If the bootable ISO fails to run after being applied to a bootable USB, change the server boot mode to BIOS or UEFI and attempt the procedure again. If the bootable ISO continues to fail, it is recommended to download the ISO file again or try applying the image to a different USB drive.
