I have lenovo E420, windows 7 preinstalled on my laptop the first time I bought the laptop. Then I installed windows 8. Now I want to install Ubuntu 12.04 alongside with windows 8.
I google and found this website where it describes how to install ubuntu alongside with windows 8. This is the link: http://www.everydaylinuxuser.com/2013/09/install-ubuntu-linux-alongside-windows.html
I followed every steps on it. But then I stucked where I need to disable the secure boot. It seems since my laptop was not windows 8 preinstalled, when I went to the advanced options on windows 8 there is no "UEFI firmware settings". Thus I can't turn off the secure boot. I tried to look on bios and I couldn't find anything that related to turn off the secure boot.
Please tell me other way to disable the secureboot on windows 8?
