Have a Asus ROG G750JX now here is the issue I am having. About a couple of weeks ago I was able to choose my harddrives and USB. Now the only thing I changed was in the BIOS which I launched EFI and now I only have the option to choose 1 HD and not 2 and it will not boot into my USB. Everything works fine at the moment but I will not be able to install dual boot ubuntu as this does not even give me an option to install. I do not know why this happen I have reset my BIOS and have AHCI choosen I cannot even get my RAID working as well. If anyone know of this issue or has come across this issue let me know.
