I just downloaded the GM from Apple and when the installer reaches the point where it asks which drive to install to, I have 3 options. One is my legitimate Windows partition, another is the Lion install partition or whatnot and the third is another Windows partition that doesn't really exist. I can't select any of them and I can't get the installer to quit back to Snow Leopard. I went to the startup disk option and the only option it gives me is to boot into my Windows 7 partition and it won't let me boot there. Says it doesn't have enough information. What can I do to just get the installer to quit? This is a secondary machine and I don't really do time machine back ups on it, but now that I think about it there are some things on here that I do need, so if anyone could give me any kind of advice aside from formatting. Thank you.
