I'm trying to install CentOS 6.5 from USB, which goes like a charm until certain point. I'm going crazy with this, I even uploaded a video to YouTube so you can see what I mean.
I have a 750GB HDD with 2 partitions, the first one for Windows is with 80GB and the second for CentOS which I give 25GB for /root, 2GB for /swap and the rest for /home.
Everything goes well with the installation assistant: date, root password, partition configuration, etc. But when I finish with partitioning, the next thing if the boot screen, in which I let everything by default (the Other /dev/sda4 is Windows partition) and when I press Next you can see some missing repodata rare error which it seems to attempt to go to internet. In Repository Type I choose HTTP/FTP and put my proxy configuration. By the time I did the video (as you can see) I didn't put any repository url and you might think that's the problem... well, even writing it, it shows me the same "must specify http, https or ftp valid url...".
I really have no idea how to move forward.
