I'm also having this problem. I tried @gdeepankar solution but without success.
I'm able to click in continue in language selection, but it freezes on keyboard layout selection. I also have a nvidia card (GTX-1050). It's a Acer A715-71G laptop. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1767594 Title: Ubuntu-18.04 Installation/Upgrade freezes/does not work.
