Unable to Dual Boot Ubuntu & Windows 8

[ulzaron]

Hi, I am having a problem dual booting Ubuntu onto my new windows 8 machine. It is a UEFI based machine with 128 GB SSD.
I ran boot-repair as asked to but it did not work.
The following pastebins were generated:-

1. Ran once from "try ubuntu via bootable DVD"
-http://paste.ubuntu.com/1494446/

2. Ran twice from "try ubuntu via bootable DVD"
-http://paste.ubuntu.com/1494470/

Ubuntu is not able to detect windows 8, the computer boots straight to windows 8 upon installation of ubuntu. I know ubuntu has been successfully installed on a partition that I created for it via the installer.

Could anyone help me out?

Thank you.

Please run Boot-Repair --> Advanced options --> tick "Backup and rename EFI files" --> Apply.
Indicate the new URL that will appear, then reboot the pc and tell us what you observe?
