I have Windows 8.1 on my HP Pavilion G6 and would like to replace windows with Ubuntu 14.04 but what option do I choose when it comes to the installation part? I noticed it wont detect my Windows 8.1 so should that matter if im going to replace it with Ubuntu? Should i choose the Erase Disk option and then install? Secure Boot and Fastboot and all other options have been taken care of but would like some further instructions from someone a little more experienced.
