So I've partitioned my Windows 8 drive and allocated 200GB for Ubuntu (13.10) and 10GB for swap. Everything seems to have installed correctly from my USB drive. When Ubuntu tells me to reboot before I can start using it, I do so but am not presented with the option of selecting which OS to boot into. I have tried checking my BIOS to see if it might be there but to no avail. I have tried Boot-repair (which gave me the link: paste.ubuntu.com/6321477) which did not work either.
By the way, I have a 64-bit machine.
