I already did that, of course. 2 steps ahead of you.
After I tried to install via Wubi, I found out that Wubi was already a part of the install. I tried to install using the method off of the cd AND I also tried mounting it with Daemon tools and running the install off of my HD, but I get the exact same error as I got with the Wubi installer both time.
As soon as it finishes with the checksum, the analyzer starts for half a second and then it crashes.
I'm on the Live CD right now. I'm loving everything about it so far, especially hyped about the pre-installed apps. Almost enough to make me leave XP....almost.
