Error upon installing Ubuntu 12.04 (also 16.04 and 17.10)

[Ivo de Andrade de Deus]

I'm attempting to install Ubuntu as a dual boot alongside with Windows 10 on my notebook, a Lenovo Ideapad, but all versions I tried to install so far have worked. I've asked on AskUbuntu about this issue (https://askubuntu.com/questions/1018568/issues-installing-ubuntu-16-04-lts-stuck-on-linux-signed-image-4-13-0-37-generi), but nobody seemed inclined to help, so from there I resorted to try installing other versions of Ubuntu other than 16.04, as 17.10 and 12.04, but they all seem to either fail (12.04) or get stuck in not finding Source IDs (16.04 and 17.10).

I would be more than happy to provide any additional info, and I thank your attention and support beforehand.
