Using Ubuntu on a Windows 8 Laptop: because of UEFI more problems as expected

Today i tried to install Ubuntu on a Windows 8 Laptop. First thing: you have to use 12.04 or greater because Windows 8 uses secure boot with UEFI.

But after the first boot with a USB-stick i got:

(initramfs) Unable to find a medium containing a live file system

?? - If you ask google you get something like: Do not use a usb 3.0 port... Great... There is no usb 2.0 port on my device....
So just trying around with a usb 2.0 hub  - does not work
Looking inside BIOS i found XHCI:

And after that Ubuntu is installed without any problems... (hmm - that is not really true: resizing the Windows 8 partition could not be done via Ubuntu installer - but just do this in Windows 8 - this will work without any problems).
Ok - end of this posting? Unfortunately not, because Windows 8 does not boot anymore.
I think this is ok ;-)
Asking Google gives the following solution: Just use Boot-repair.

sudo bash
add-apt-repository ppa:yannubuntu/boot-repair
apt-get update
apt-get install boot-repair
boot-repair

And after that the grub menu looks like this:

But now rebooting works like expected (with Ubuntu and Windows 8).
