If you wish to update the system BIOS in a Linux environment such as Ubuntu, then you can get some help here.
As Linux and Ubuntu distributions are becoming more and more popular on Dell systems, there are more situations where a Linux only environment is present.
If your system is listed at https://fwupd.org/lvfs/devicelist then it supports UEFI capsule updates and can be updated natively within the OS.
Ubuntu 16.04 and later natively will notify you for BIOS updates. The system will regularly check for BIOS updates automatically. When an update is available, a popup will be displayed to flash the update
If your system or Operating System does not support UEFI capsule updates:
For newer systems (post 2015), refer to Section 2 below
All Dell systems from 2015 and later support flashing an updated BIOS from within the boot menu. Follow the directions below to update the BIOS on these systems.
Users will need to format a USB storage device as FAT32
On Ubuntu 16.04 and later, this can be done by following these steps:
Figure 1: Find Disks app
Plug in a USB storage device such as a Memory Stick
Click or touch the Ubuntu dash icon
Type disks to search for the Disks application
Figure 2: Disks app
Click on Disks
Figure 3: Format Volume
Select the USB flash drive on the left. (1 in Figure 2 above)
Look at the Partition Type below. (2 in Figure 2 above)
If the partition type contains FAT32 it’s already formatted properly
If the partition type is something else, it will need to be formatted
Click the gear icon above Size (3 in Figure 2 above)
Make sure that Type is FAT
Click the Format button
Visit www.dell.com/support/drivers to find your system
Select the BIOS update, and download using your web browser
Navigate to the Downloads folder, and copy the BIOS to your USB disk
If the system isn’t already plugged into a power outlet, plug it in now
Reboot the system, and press F12 at the Dell splash screen
This will bring up the One time boot menu (Figure 4)
Select the option to BIOS Flash Update
Figure 4: One Time Boot Menu
In the popup, navigate to your USB disk and select the BIOS you downloaded
Once the update has been completed, the system will reboot automatically

For older versions of Linux and Ubuntu and on systems that are pre 2015, you will need to update the BIOS using the following method:
Users will need to create a bootable USB storage device with FreeDOS on it to proceed with flashing the BIOS.
The latest BIOS for the system, which can be located at www.dell.com/support/drivers
The FreeDOS Base ISO 1.0, located at www.freedos.org/download
UNetbootin, which can be installed by going to the Software Center in Linux, and searching for UNetbootin and then installing it.
After UNetbootin is installed, run the program and select the Diskimage option, and set to ISO and then select the FreeDOS Base ISO file that was downloaded earlier.
Select the Type as USB Drive and the drive as /dev/sdb1 and click OK.
Use the image below as a sample of what the UNetbootin screen should look like.
Figure 6: UNetbootin screen
After this operation is complete, copy the BIOS exe file to the USB storage device.
Now move on to Section 4
After the BIOS flash file has been copied, reboot the system, and press F12 at the Dell logo to bring up the "One time boot menu"
Select USB Storage Device to boot from the USB stick.
Once the system reaches the boot menu, choose the fdos option, then choose safemode
Once the boot has completed, it will show an A: prompt.
Switch the drive letter to B: or C: (The drive letter assigned to the USB memory stick)
Type in the filename of the BIOS flash file to begin the update process e.g. O9010A12.exe and press Enter
Once the update has completed the system should reboot automatically
