How to do BIOS/UEFI update on a Ubuntu system?

I am following these instructions, and similarly this one.

I downloaded the BIOS update executable and put it into a USB drive, then after reboot I select BIOS update, where a GUI asks me to select the file. This is where I get stuck, as I cannot figure out how to select the file and continue:

Please see the attached Pics. I have used "Disks" in Ubuntu 18.04. things may be slightly different with your Ubuntu 17.10

Assumptions: System is UEFI Capable

1. Download the latest BIOS from
2. Keep the empty USB in the system you want to use for Updating BIOS.
3. Open "Disks" from your Ubuntu 17.10
4. Select the USB from the left panel of "Disks"
5. Click the settings/gear icon below the "Volumes" and "Click Format Partition"
6. give some name in the "Volume Name" prompt.
7. under the "Type", Select "For use with all systems and devices (FAT)
8. Click "Next" & "Format"
9. wait for "Disks" to finish the process and Confirm the "Partitin Type" is exactly W95 FAT32 (LBA)
10. Now copy the already downloaded file XPS8920_1.0.15.exe in to this USB.
11. Reboot the system, and press F12 at the Dell splash screen This will bring up the One time boot menu Select the option to BIOS Flash Update 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
