(Get the code!)
A workaround...but not a complete work around...
So I do believe I figured out a "solution" but it literally makes zero sense and indicates a problem with the Dell BIOS and potentially some oversight in the kernel?
Built 16.04.5 Desktop image with Rufus 3.3.1400.
Partition Scheme: MBR
Target system: BIOS (or UEFI-CSM)
All other options default.
1.0 So with the computer in UEFI Boot, Secure boot off.
Hit F12 to get into "One time boot menu".
In the "One time boot menu" you can select "Legacy" and UEFI boot options (e.g. USB Boot Device under legacy menu, and then under UEFI it shows the devices one being this Kingston USB device as a boot option).
1.1 In the UEFI Boot mode if you select the UEFI device, the system will not boot as describe above, no combination of nomodeset, acpi=off, noapci will work. The system hangs at a blinking cursor or in some type of error code as listed above.
1.2 In the UEFI boot mode if you select the USB boot drive under LEGACY, it boots into the selection screen correctly of (Install Ubuntu, Try Ubuntu, etc. menu). You will have to add the F6 options of nomodeset, acpi=off, noapci and then select the "Install Ubuntu" option and then the important part...YOU CANNOT BE USING ONE OF THE DISPLAY PORTS ON THE VIDEO CARD, YOU HAVE TO BE USING THE DVI PORT! At this point you will have the Desktop installer functioning.
I didn't really like this "solution" since you would have to be using the DVI port, so I dug some more...
2.0 I switched the machine into "LEGACY BOOT MODE, SECURE BOOT MODE OFF". In the one time boot option (when you hit F12 during POST) the boot menu will still show "LEGACY Boot Options" and "UEFI Boot Options". The same as before. However the results are different.
2.1 While in LEGACY boot mode in the one time boot option if you select the USB boot drive under LEGACY you get the SAME interaction as what I stated in 1.2. (e.g. to get the Installer Desktop GUI to show you have to add the nomodeset, acpi=off, noapci flags and then be plugged into the DVI port)
2.2 This is where it gets fun...while in LEGACY boot mode, select the USB boot device under the UEFI menu. The "Try Ubuntu, Install Ubuntu menu option shows", hit 'e' to edit the boot string, add the "nomodeset" flag hit F10, AND IT BOOTS CORRECTLY, with the DisplayPorts.
So why is this stupid? The computer has to be IN LEGACY BOOT MODE AND you must select the boot option from the UEFI menu. Which makes literally zero sense. Why would I need to put the computer in LEGACY mode to only select the boot option from the UEFI menu. You have to add the nomodeset option as well, but the options you have to select are quite absurd to me.
So for anyone running into this with BIOS 1.8 in a Dell Precision 5820.
Create USB drive that will boot in UEFI mode. You can use Rufus that will boot in UEFI mode or Legacy mode, but I doubt this matters.
Set the computer to LEGACY BOOT MODE (THIS IS IMPORTANT)
When the computer is posting hit F12 to enter in the one time boot menu.
Select the USB device to boot from WITHIN the UEFI menu (you will see both).
Highlight the "Install Ubuntu" option and hit 'e'. On the "Linux" line before the "---" change the line to be "[...] nomodeset ---"
Hit F10 to boot and you will get the Desktop installation menu.

The only problem with this is that with noacpi enabled the OS only sees a single core, which is obviously a problem.
