I'm installing 10.10 as the only OS on an older P4 computer. Just 1 gig or RAM and a 40 gig HD. I'm installing from a CD iso file. It has gotten as far as asking for my name and a user name and password, it seems to load most of the files and the progress bar is nearing the end, but just stops. I've no idea what to do. It's my first experience with Ubuntu.
