Hi there.
Yeah, if you are new and "just want it to work", stick with 9.1 until 9.2 is official. They are saying Oct 15(ish) for
Mandrakeclub members, and then 2 or so weeks afterwards for everyone. (As an aside, if you like Mandrake, please do consider financially supporting them via Mandrakeclub).
As for the Windows partition, MDK should have auto-detected it and mounted it for you (usually as /mnt/win_c) but if you don't see it, you'll need to create a mount point. There's a good article on
Linux World that can help you with that.
