Tried to upgrade Zorin but gets stuck in TTY1

So I was running Zorin OS 9 (Dualbooting Windows 10 on UFEI mode and Zorin/Ubuntu on CSM Mode) when I got a prompt asking me to upgrade Ubuntu 15.10 Willy Werewolf, I clicked yes when later on to the upgrade the screen starting flashing black a little, and when it was on "installing packages" or something, the screen went blank and I couldn't get out of the blank screen so I rebooted the computer and now when I try to boot into Zorin/Ubuntu, I only get a TTY1 screen asking for my login and when I log in, it's just in TTY1 Mode. Is there anyway I can get past this? If I can't fix it, can I get reformat my Zorin partition and reinstall everything?

Can we be clear on one thing, have you got Zorin and Ubuntu alongside Windows 10?
