Funny, I just tried to install Lycoris(Redmond) last night and I ran into the exact same problem. I finally got the install to work, however. When the part of the install came up for managing the partitions, I selected the "for experts" partition management feature rather than letting lizard find the partitions for me (like I did at first. That's when I got what you are talking about). After formatting the partitions, everything installed. I couldn't play the card game during the install, though. The install crashed and I had to start over.
Now I'm struggling to get my sound card and modem to act right. Otherwise, it seems stable. But what fun is a computer with no internet or sound?
Hope that helps. I'm no expert in Linux, so I couldn't tell you what to do next! I came here looking for some answers, too, and I just happen to see you are trying to install the same thing. Maybe you can do what I did.
Take care,
