Partition failed is prob. an error on your windows partition, prob. a cross linked file. I'd boot in windows and run scandisk, if your lucky scandisk will finish before windows crashes. Then try installing Mandrake again.
In Mandrake installer, I'd do custom partition either way you go. I'm not sure but you might not have enough free space, maybe that's what It's complaining about. This may sound funny, but be sure you are shrinking the windows partition before you try to add the linux partition, then add the linux partition to the empty part (I think it is the "white part" in mandrake.) Don't forget a linux swap partition also, maybe that's why it is complaining. That's all i can think of, sorry if I was just stating the obvious.
