How do I Dual Boot Windows 8 UEFI and Ubuntu 12.10?

I have got a new Samsung Series 7 laptop with Windows 8 where I tried to install Ubuntu. It is a 64-Bit system which uses UEFI and has "Secure Boot" switched on in the BIOS by default. After I switched if off (and set it to "UEFI and CSM OS") I was able to install Ubuntu (Ubuntu 11.10, which recognized Windows as Windows Vista, although it is Windows 8), by booting from CD with Settings/Change PC Settings/General/Advanced Startup in Windows 8.

But after the installation and the restart of the machine somehow ignored Ubuntu and booted only Windows 8. Then I tried to reinstall Ubuntu 12.10. It still only boots Windows 8. Then I tried Boot Repair, which was not really helpful. Any ideas how I can create a dual boot system with Windows 8 and Ubuntu 12.10 ? Here is the link that Boot Repair generated: http://paste.ubuntu.com/1368624/ Is it necessary to create an extra EFI partition with GParted?

Boot on your Ubuntu-Secure disk

Choose "Try Ubuntu"

Connect internet

Open a terminal and type the following command (this will update Boot-Repair):
```
sudo apt-get update; sudo apt-get install -y boot-repair boot-sav
```

Run Boot-Repair, click Recommended Repair. Write on a paper the new URL that will appear.

Reboot the pc, you should get a GRUB menu with access to both Ubuntu and Windows. If any problem, indicate the new URL.
