Reboot using a rescue disk (DVD, live CD, net install, who the bleep
cares which). I haven't upgraded using any disk since maybe Fedora 10.
If I recall correctly the rescue process tries to find your file
systems. Does it succeed? It sounds like it should.
When you get to a command prompt in rescue mode can you
"chroot /mnt/sysimage" or wherever the rescue disk mounts your existing
file system at? Does it look like everything is still there?
What argument are you passing to grub2-install? /dev/root?
Does /dev/root exist? From what I've read and had to do the argument to
grub2-install is something like /dev/sda. What is/are the disk
device(s) in /dev? Which device that you see has the MBR? If you run
grub2-install on the proper device, e.g., /dev/sda, what happens?
If grub2-install worked then before you reboot disable selinux
("SELINUX=disabled" in /etc/selinux/config, I think). Reboot and see
what happens. If you can boot up OK then re-enable selinux. What
happens? Does your graphic environment (KDE, Gnome, whatever) still
work?
I upgraded using yum. I also had to run grub2-mkconfig in addition to
grub2-install. Took a little digging around to figure out that I needed
to do that also. When I first rebooted I just got the "Grub>" prompt.
