I just built my computer. Brand new everything. I tried to install ubuntu. I filled out the screen that asks you to assign a name to the computer, create a password, etc. When tried to continue, the screen said that I had an "unofficial copy" of ubuntu. What did I do wrong.
Now when I put a usb in the screen is black and says GNR GRUB version 2.02 at the top. What do I do from here? I've been Googling all day and have gotten nowhere. I tried boot-repair-disc and nothing happened.
