[ubuntu] Problem booting windows 8 UEFI with Ubuntu 12.10

Hi

I installed Ubuntu 12.10 alongside Windows 8 after disabling secureboot. I had to mess around with /etc/grub2/40_custom to get it to work but I did in the end..

I had to reinstall Ubuntu as an upgrade broke the graphics card drivers - but I've got stuck making it work again. I thought I did the same steps, but it's failing with an error.

Thanks!
