Comment 7 for bug 1286047

Please see attached PDF which contains screenshots and further explainations. I know the PDF turned out quite large due to the mobile phone fotos but I believe it should clarify what's going on.

As of the information provided with the attached PDF, I think that the problem is introduced once Ubuntu 13.10 is installed by using an USB Stick without the UEFI option. This way the boot record ends up pointing to "sdb" rather "sda" since the installer orders the USB Drive as "sda" and the RAID disk as "sdb". However after the installation has finished and the USB Stick is removed, there is not "sdb" drive and thus no bootable device is found and the UEFI/ BIOS user interface shows up instead.
