How I updated my BIOS on my Dell Latitude 5520 Linux Laptop

For starters let me state that my Dell Latitude 5520 is an experimental machine and I'm nowhere close to being proficient with Linux so there may be a way to upgrade the BIOS directly but I couldn't find any info on this so the following is how I updated the BIOS on my laptop.

The problem I faced is that the BIOS update file for the 5520 is an executable application designed to be run directly from within Windows. If this an be done a better, easier way, directly from Linux, please post how it can be done for myself and others that are not Linux proficient. Here's how I did it on my Linux 5520 laptop.

I download the BIOS update from DELL on my Windows desktop, along with a copy of HIREN's BOOTCD-PE ISO file from their website and a updated copy of Rufus portable edition from their website. I then used Rufus and the HIREN's ISO file to create a bootable WIN-PE drive on a 32 GB thumb drive. Once the bootable WIN-PE drive was created I copied the BIOS update application to the root of the thumb drive.

Once the thumb drive was ready I inserted it into a USB port on my Linux laptop, restarted the laptop and on my 5520 I immediately pressed the F12 key to enter the Boot option menu and then select the thumb drive from the list. Once selected the 5520 booted into a stripped down PE version of Windows and from there all I had to do was open File Explorer, find the BIOS Update application and launch it. Once launched the BIOS update process started up, restarted the laptop in BIOS update mode, updated the BIOS and when finished rebooted right back into my Linux Distro.
