My laptop is lenovo g580 with win7. I want to install ubuntu 15.10 on it, dual boot with windows. I disabled uefi in bios. Installation goes, but then sometimes a message installer crashed, or no such message, but it doesnt install. What ubuntu version should i choose for this laptop? What is the reason it doesnt install, because it doesnt support this hardware? I guess the latest version would not work on it.
