I have yet to install grub2 on RHEL/Fedora but on Ubuntu update-grub
is a shell script that simply calls grub-mkconfig.

Getting a grub cli means AFAIK that grub cannot find /boot and/or its
config file. You can use the cli just as in grub1 to boot.

(On Ubuntu, the config file is called grub.cfg. I assume that running
"grub-mkconfig -o grub.conf" ensures that grub2 knows that you have
called it grub.conf as in grub1.)
