Stuck in UEFI BIOS EZ mode PLEASE HELP!

[desperateLost]

Dear readers,

I recently wanted to install Ubuntu 15.04 alongside Windows 8.1. So I downloaded the .iso file and made my USB stick bootable.

I entered the UEFI BIOS and clicked on the button "Boot Menu". A new windows appears and I chose for my USB stick. But then the screen goes black and nothing happens, nothing for minutes.
I shut down the computer and started it again. Several times I did the same thing, in the hope to that it will work, but it did not.
The next I did was clicking on the other options, such as "Advanced Mode". When I hit "Advanced Mode" a window appears and then I click "Ok". As you already may have guessed, the window goes black again. This also happens if I hit the "Shortcuts" button and then one of the options that appear.

So this is what I tried to fix it. I shut down my computer, pulled out the plug and pulled out the CMOS Jumper. I put the Jumper into the other pins. Then I pressed the on-off button for 15seconds to reset it. Put the plug back in and started the computer again. Again I tried to boot from the USB or enter the "Advanced Mode". But the screen goes black again.

Then I tried to do the same, but this time I pulled out the CMOS battery instead of the Jumper. Again no result.

The weird thing is that I managed to install Ubuntu 15.04. But it happened unexpectedly. After I had rebooted my PC for the one billionth time I suddenly get the installation screen in front of me.

My specifications:
CPU: Intel i7 4790 @ 3.6GHz
GPU: Asus GTX 970 Strix
Mobo: Asus Sabertooth Z87 Mark I
RAM: 4x4GB Kingston HyperX Fury White
Power: Corsair RM1000
Memory: 1TB Western Digital HDD and 120GB SanDisk SSD

The BIOS software version is 1803.

I have a wireless Microsoft all in one keyboard and a RAT 5 mouse.

Note: I first had 4GB of RAM, then I purchased another kit. It is exactly the same kit. But before I purchased the kit it did not happen. After I purchased the kit it happened. Maybe it was already broken before I purchased the kit. But I can't know.
Note2: I am not a computer guru, I do not know a lot of terms and words. I do know the popular terms tough, but please keep in mind I am not an expert.

Please help me out. I am hopelessly lost and stuck in EZ mode.

Thank you for reading and taking the time to answer.

Hey desperateLost. I've checked on Asus' website and your BIOS is well out of date. The latest version is 2103 whilst you only have version 1803. Updating the BIOS should fix this issue completely. You can find the BIOS update here: https://www.asus.com/uk/Motherboards/SABERTOOTH_Z87/HelpDesk_Download/ There's also a digital version of the manual available which will explain how to update the BIOS. With USB BIOS Flashback, this is fairly easy.
