Comment 10 for bug 506670

I managed to get the problem resolved though it was a bit of a pain. Had to burn a desktop livecd and then apt-get several things (mdadm, gdisk & friends) into the running system in order to create a BIOS_Boot_Partition. Fortunately there was some space left over where I could put this partition. It would be very helpful if parted (& if possible gdisk) is included in the alternate CD as you're pretty stuck in terms of having a powerful partition table editor to hand if you've got a gpt partition table and are trying to install from alternate cd...
