Sorry to hear about your problem.
How long have you waited already? It can take some time, but you can usually at least see progress being made! If you haven't already, maybe leave it for 1/2 hour or so to see how it gets on.
Otherwise, it would be good to try and get a little more information.
For starters, if you change the theme to Ambiance (by clicking on 'Live Session User' > System Settings > Appearance and looking at the bottom of the window) that will remove the pink, and let you see information about what Ubiquity is trying to do when the bar stops moving. This will let us narrow down the problem a little further.
In particular, with a 2Tb disk, it could take a fair while for the partitions and filesystems to be created.
If you try that and let us know how you get on, we can then take it from there
