I was using the computer and I went back to Windows and it launched in start-up repair. Now when I try to start Ubuntu this screen comes up that says something about grub files and talks about giving some command. Then it has
grub> and a blinking cursor.
I honestly don't know how to get rid of it and I would just uninstall and reinstall Ubuntu but I don't want to lose my files which I hadn't backed up. Help?
