How to convert Wubi install into regular install?

12.04 LTS wubi "F: image on partition" and "windows7 on C:"

Wanted to test before using full install. However I kinda customized the looks and got lots of SW installed and now I don't like the idea of reinstalling the whole thing all over again :D...

Due to previous cloning my broken 320GB HDD to 500GB HDD I had ca. 180GB unallocated which I made as NTFS and it's drive F:. I would like to make that drive ext with full ubuntu 12.04 but I'd like, if possible, to make my current wubi installation a full one.

Now I read that it's possible to migrate wubi to full. But..

Is it safe with Grub and windows 7 installed?

Is there alternative how to keep all the installation/current state of ubuntu
and get it to the new full install?
