linux-tui might not be in your menu. It is there normally, but you might have unchecked that option.
Or you might have chosen something that disables the wait period. With no wait, there's zero time to choose anything.
This probably won't work, but try it: When it hangs, press Ctrl-Alt-F3 . It might get you a text screen. If it does, someone may be able to help more.
Did you use the graphical GUI installer, or the text-based one? That info would help.
Edit: I see from the other post you used the GUI, right?
