[ubuntu] Ubuntu 13.04 won't give option to install alongside windows

view story

http://ubuntuforums.org – When I try to install ubuntu 13.04 off a live usb, I do not see the option to install alongside windows 8. The version of windows 8 I have is one I upgraded from windows 7, so it uses bios. I used to be able to install ubuntu 12.04 and 12.10 when I had windows 7 installed. When I upgraded form windows 7 to 8 I had an install of 12.10. If I remember correctly I wasn't sure exactly what to do to remove it and now I think there is probably some funky thing with my partitions that the installer doesn't like, any help would be greatly appreciated. Thanks. (Hardware)
