I've tried Ubuntu, Mint, etc. No luck with any of them. The live CD works fine. I've tried this with 2 different hard drives, no luck. UEFI is turned off and legacy mode is on. I've tried turning nVidia Optimus off too. All I get is a blinking cursor. Can anyone help me? I was under the impression that the W520 is very Linux friendly, so far this has been pretty discouraging. Any help would be appreciated.
