authentication Problem


I had red Hat 9 installed on one of my computers. I updated to fedora 3, by simply inserting the CD at boot, and then followed the instruction, it FOUND my red hat 9 and ask me if i wanted to format or to upgrade. I choose upgrade, it did not ask me anything else from there on. However we it restarted I got the grub and was able to choose from fedora 3 or red hat( so far so good), Then I choose fedora and at the log in all the users can't log in (not even the root) IT SAYS AUTHENTICATION FAILED. AND IF I ENTER A USER WHICH DID NOT EXIST THEN IT SAYS "INCORRECT USERNAME OR PASSWORD"

You can use the Fedora CD and boot your computer in rescue mode. After initial start up, type linux rescue. Follow the prompts, it will search for any partitions that have linux installed. Once it locates an installation you will be able to mount it at something like /mnt/sysimage. Then you'll get a command prompt and essentially be root. What you can do at this point is use chroot /mnt/sysimage /bin/sh to gain access to the installation. Once there you should be able to reset the password for the root user.
