I just got a new Lenovo Yoga 720 and I'm having trouble installing Ubuntu alongside Windows.
After I boot to Ubuntu Live, in both 16.04 up to 17.10 the touchpad does not work, but the touchscreen, mouse, and keyboard both do.
But the main issue is that when I get to the part of the installation "Installation type", there is no screen to choose "Install Ubuntu alongside Windows Boot Manager." And I did make the partition on Windows and allotted 80 gb for Ubuntu.
Instead, it immediately goes to the screen that you would get to if you had chosen the "Something else" option, where you manually partition I think.
It goes straight to this screen
Is installation on the Yoga 720 not possible? If so, do I just need to wait until the next version of Ubuntu to do so? I see that the Yoga 720 is not on the list of certified Lenovo devices yet on Ubuntu's website.
Or is the issue not specific to the Yoga 720?
How do I install Ubuntu and get the touchpad working?
