Hi again. I tried the DVD in rescue mode but I'm not sure I quite followed what it did or what it might have supposed to have done. I did get a shell at one point so I perhaps naively tried yum install evolution and likewise with gnome, but yum was not a recognised command. Anyway, I restarted the system and it got hung up when going through the startup process. I think it was when it tried starting "local". I tried the whole process again, this time entering in the shell the suggested "chroot /mnt/sysimage" and restarted. It went through the list of processes it was starting then got to the same point as earlier with the f/infinity fedora logo and stopped.
Again, I'm a computer/linux user in the sense that I'm fine when it works or even slightly goes wrong but in this case I'm a bit lost.
