Hi after installing xubuntu in windows and having it not work I've decided to just dual boot the old fashioned way. I have one question though, how do I completely uninstall the 30GB I installed xubuntu in on my windows partition?

You delete it with the application gparted like I said, run the Live CD, open a terminal and tpye gparted , now from here locate the 30GB partition.

I know this to dual boot but my question is how do I remove the 30GB install 1f40 I made in windows for xubuntu thrugh wubi or whatever its called.....I apoligize if you did mean this to remove that I have never used wubi before.

Boot your computer from CD, run the Live CD mode and from here you can run an app called gparted to edit partitions.
