That would have been my suggestion, a do-over. I hate when stupid crap happens during an install but at least there's not much work invested yet. When I start getting further along, I start making sure there's restore points, so I can go undo driver or program changes if needed. After installation and updating of Windows, plus a few tweaks while waiting for that, one of the first programs I load is Acronis, so I can start making real backups, just in case.
Sounds like it's all working, which is good, but for what it's worth - keep an eye on restore points and considering backing up the entire thing once everything's done, and maybe a few times in between too.
