I had problems booting with Ubuntu 9.10.
I tried different ways of installing until it told me if I wanted to make my drive bootable or something like that.
I said yes and Ubuntu ran some stuff, after that I was able to boot from the CD.
I'm sorry that I can't be of more assistance, but it's been a month since I did it and I can't remember how I did it.
Maybe if you try searching google.
I'll do the same and if I find something I will post.
