I have a Samsung Chronos 7 laptop (NP770Z5E) pre-installed with Windows 8, and I wanted to install Ubuntu 13.04 alongside it, so I can dual boot.

Here is what I've done:

Updated BIOS to lastest version (P04ABU) using Samsung Updater

Reduced Win8 partition by half, I left the others untouched

Created a bootable USB stick using http://unetbootin.sourceforge.net/ and a Ubuntu 13.04 64-bit image

Disabled FastStartup on Win 8

Disabled Fast BIOS Mode

Boot Mode changed to CSM OS

Update:

Also disabled Secure Boot (I had to disable it in order to select CSM OS)

After that I saved the BIOS settings, and shut down the computer. I plugged in the USB drive, powered the computer on, entered the BIOS and tried to change the boot order. Oddly, there was only one option in the boot order screen, the USB drive (HDD didn't show up in the boot priority screen).

I ignored that and installed Ubuntu. I've created 3 partitions from the unused spaced left: a 8GB swap, a 100MB BIOS boot partition, and the rest to ext4, mounted in /. Boot loader installed on /sda.

After a reboot, this message appears:

All boot options are tried.

Press <F4> key to recover with factory image using Recovery

or any other keys for next boot loop iteration.

So I went to the BIOS to change the boot device priority, and the list is empty!
Enabling Secure Boot and Fast BIOS had no effect.

I used the Ubuntu Live USB to check the disk contents, I can see the Ubuntu and Win 8 partitions.
I've used Boot Repair (using the Recommended Repair), with no avail, the Boot Repair log is here: http://paste.ubuntu.com/5953562/

Boot Repair showed me a message about the system being a"EFI system". I suppose that means that I should have checked out the advanced settings.

I don't know how to proceed. I don't know if it's a good idea to "recover with factory image" since I have modified the original partitions. Maybe I need to experiment with Boot Repair's advanced settings.

You installed Ubuntu in BIOS/CSM/Legacy mode using the protective MBR. You should be able to boot just Ubuntu from UEFI menu in CSM or BIOS mode. That would have UEFI off and with UEFI off, there is no secure boot option.

Some systems only boot Windows with secure boot on. Others boot with it off, but Windows is installed in UEFI mode. Since UEFI & BIOS write hardware info to system differently you cannot dual boot from grub menu but only by going into UEFI and turning it on for Windows or off for the BIOS install.

Better to install Ubuntu in UEFI mode and then you should be able to dual boot from grub menu. But some systems will only boot Windows with secure boot on and you have to boot the Boot-Repair program in secure boot mode to get to install the Ubuntu signed kernels that will work with secure boot.

It looks like Boot-Repair already converted your BIOS install to UEFI, but you do not have signed kernel so Ubuntu will only boot with secure boot off. A few system do not allow that or only allow the Windows efi file to boot. Then Boot-Repair has to do a work around and rename grub's shim to be the Windows file to may dual boot work.
