As it explains in tutorial, you can keep your lenovo Recovery partition if you think it might still run after install, then later cue it up to see. If not you can delete it and Extend C into its space along with the small unneeded partition at end of HD.
If your model uses F8 to trigger Recovery then it will NOT work after reinstall since it wipes out Advanced Boot Tools menu during reinstall.
If you'd prefer to run Lenovo Recovery to see how that works for your you can also try that first.
