This question already has an answer here:
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?
