I just installed Ubuntu 14.04.01 onto a 8GB USB stick using Universal USB installer just like it said on the website for windows. Once that had finished installing it onto the USB stick I rebooted my laptop and then booted onto the USB stick. It booted into a screen that gave me the options to install Ubuntu, try Ubuntu without installing and check the disk drive. I selected to try Ubuntu and it gave me a black screen. After a while my keyboard lit up and I waited for about 5 mins and I force shutdown my laptop and I am now writing this.
My laptop is a Early 2011 Refurbished 15" Macbook Pro. It has 8GB of ram, Intel i7 quad core, 1 integrated intel 4000 HD GPU and it also has a AMD Radeon HD 6490M.
I have done some research into this subject and I have not find much that relates to my situation.
I would like to say thank you in advance.
