This is the most frustrating issue I have ever run into using Ubuntu and Windows in the same machine.

I have an ASUS K46CB, 6GB RAM and preinstalled Windows 8.1 64-bits. I have successfully installed Ubuntu 14.04 LTS, also 64-bits. To do so,I followed this tutorial whenever possible. I only failed on the disable secure boot part: there is no 'Secure-boot' or even UEFI mention in my BIOS!

Screenshots from other BIOS of the same model show the option under Boot, but in mine there is absolutely none. Because of this, I cannot boot into Ubuntu. The computer loads straight into Windows.

I tried running boot repair, but got an error (i can show the log, but it's pretty long).

Does anyone know how to fix this issue?

UPDATE

I reinstalled Ubuntu. Same problem, goes straight to Window. Boot-Repair informs me that i am using Windows in Legacy mode. It excecuted with no errors this time, but after restarting GRUB was still missing. I can't turn off Secure Boot yet.

UPDATE

I tried using Boot Repair to install grub on a boot-grub 1mb partition. Still boots straight to windows. I feel like punching something

I tried to setup a "proper" Windows/Ubuntu dual-boot system, by installing Ubuntu from a USB key. However, I simply could not get the laptop to boot off the USB despite the fact that I made the appropriate changes to the boot device order in the BIOS. So I then turned to Wubi, and (to cut a long… >>> More
