I'm intrigued with the Sabayon method of booting via UEFI, but it's not working for me. My machine is set to UEFI only, with secure boot activated. When I boot via the new SL 11 installation CD (Gnome version), I get sent to a simple grub prompt.
If I use rEFInd (previously installed, as I use it to load Arch Linux via UEFI) to boot the mokmanager, I am presented with an option to register the key, which I then locate on the CD. But, after registering, I seem to be in a loop. I can exit up to boot, but then I get sent back to the simple grub prompt.
I think I, and maybe others, too, need a step-by-step guide for this special booting procedure.
