I just installed fresh Ubuntu 13.04 on my Lenovo Ideapad z570, alongside Windows 7
Grub2 has replaced Windows mbr, so I get presented with a menu, when I boot - when I select Ubuntu - the screen stays blank (purple screen) - pressing any key have no effect.
I can boot however from a USB (in fact this is how I installed it)
below is laptop configuration:
