[YLUG] Windows 8 and Ubuntu dual boot with Secure Boot?

Hi All

I know that there are quite a few of you in the group who use Ubuntu and I
have a friend who has a new machine that came with Windows 8, and he tried
to install Ubuntu with dual boot using UEFI with Secure Boot.
 Unfortunately he failed miserably to get Ubuntu to boot with Secure Boot,
and ended up having to change the BIOS settings every time he wanted to
boot the alternative OS - Windows 8 would not boot at all with Secure Boot
switched off in the BIOS, and Ubuntu would not boot with it switched on.

Does anyone have any prior experience with getting Secure Boot/UEFI for a
dual boot Windows 8 and Ubuntu system working properly? Any links to
guidance or step by step help?

I used to use Fedora until around a year ago, but I got disenchanted with
some of their philosophy and moved all my machines to arch linux, and now
have two home-built machines which I single boot arch with UEFI using
rEFInd and it took me quite a while to understand enough about UEFI to make
it work at all! However I have no experience with Ubuntu concerning UEFI
and none either with Windows 8!

I know there are a lot of problems with UEFI in general and different
motherboards and different brands of machine have UEFI implmented
differently, and for Secure Boot in particular especially for dual booting
systems built on such machines.  However although there are a number of
different ways to approach UEFI boot in linux including rEFInd ( which
really replaces rEFIt), as well as grub2 and gummiboot my only experience
is with rEFInd and only in arch linux concerning UEFI. I would like to be
able to help my friend but I am somewhat stuck in getting information
without my own Ubuntu system to tinker with.

Any hints and tips appreciated so I can pass them on to my friend.

Thanks
