I had this problem before with Fedora and solved it by deleting random lines in the GRUB2 launch commands.
This time I decided to use the Wubi install of Ubuntu. First boot was fine, but the second caused a massive amount of flickering and the screen was offset so high up I can only see about 5px of the bottom.
I tried pressing Ctrl+Alt+F2, but with the offset I have no idea what I'm typing.
I'm fairly certain sudo dpkg-reconfigure xserver.xorg or nomodeset are the way to go. But how?
