I upgraded my system from Fedora 25 to 26, and after upgrading it rebooted and I got a black screen with a mouse pointer in middle but no GUI to make a login.
There is an error on booting which says
Failed to load kernel module
What may be the problem, what should I do to make things work?
I tried to boot with changing grub entry and nomodeset=0 but it comes to the same result. Also, I tried to boot with old kernels of Fedora 25.
