I am using Fedora 15, and want to upgrade to version 16. I follow the official link Upgrading Fedora using yum - FedoraProject to upgrade my OS by the following command:
yum update kernel* --releasever=16
yum groupupdate Base --releasever=16
reboot
After reboot, OS can not start, and just print the following message on screen
could not start boot splash: No such file or directory
and the screen does not print other types of messages. I have installed many software on my previous OS, and I don't want to format my system partition. How can I bring fedora back to life without reinstalling the OS ?
