I've been fortunate that I haven't had to use the rescue functions for years, but today unfortunately I slugging through it and hopefully someone can assist.  I'd rather not have to reinstall just because I can't use chroot.

I was able to figure out that you have to install the server livecd to get to the troubleshooting tools, apparently, they aren't on the workstation.  It might be helpful to point that out.  When looking through the online docs I couldn't find it... maybe I just missed it - but it doesn't seem to be in an obvious place.

Then when I finally was able to get into boot the server livecd and go into troubleshooting, and rescue a Fedora System...

the process was able to find my installation and mount it under /mnt/sysimage

Then it says:  If you would like to make your system the root environment, run the command:

chroot /mnt/sysimage

I then get the response:
chroot:  failed to run command '/bin/bash':  Input/output error

I checked and it is there.  What's going on?
