I am using the following system:
Lenovo Legion Y520-151KBM with Windows 10, Intel Core i7, 16GB RAM, 256GB SSD + 1TB HDD, NVIDIA GeForce GTX 1060 Max-Q (6GB).
I am trying to install Ubuntu 16.04 on my system via dual boot using a USB stick. I clicked the Install Ubuntu option in the grub menu after which I get the Ubuntu desktop. After clicking the Install Ubuntu icon on the desktop and going through the language selection, wifi connectivity and third-party software installation screens, I get this screen for Installation type:
...which is different from what I should have gotten. After clicking on the Change button, I got this error message.
I am not able to proceed with my installation.
