Emergency Mode Can't Boot
I recently tried to switch my iMac over from macOs Sierra to Fedora 25 and I came up with some issues. The installation went fine and then it told me to reboot to finish. I clicked on "restart" and everything seemed fine. The blank fedora logo appeared and it started to load but it didn't finish loading and didn't boot; occasionally it does come up with the "f" and the blue background. It then kicked me to Emergency mode. Picture here ---> http://i.imgur.com/pmhGO9R.jpg I don't know where to go from here.
Try to reinstall since there is no data to save. Maybe a step was overlooked during the initial setup. What i read in the picture has me wondering about the hard drive being in good shape.
