I have just tried to boot from a cd burnt from http://cdimage.debian.org/cdimage/unofficial/efi-development/upload1/debian-wheezy-amd64-efi-test1.iso
I get the following message: Welcome to GRUB! Error: "Prefix" is not set. The screen then clears and a pixel-ised blue screen is shown which is unreadable. Looks like a corrupted GRUB Boot screen. I have had this error with the Lenovo S205 with any GRUB2 distro except SUSE. Many Thanks, Roy Barnard
