I have installed Ubuntu 12.04 on a Lenovo y510p. There are two issues I'm not able to resolve -

  1. Before the Grub screen loads, I always get an efi disk error. I have tried turning off fast boot and secure boot as well as doing a smart check on the disk, but the error always comes up for 2-3s and then Grub loads and I'm able to select and load both ubuntu and windows 8. Can someone please help me resolve this?
  2. When Ubuntu loads there is a black splash screen with some messages, for 1-2s, before the ubuntu logo comes up in the middle of the screen with purple background. I'm not sure if there is some error with ubuntu loading or just that I need to disable splash screen?

the boot repair is here http://paste.ubuntu.com/6817526/

Thanks!
