This question already has an answer here:

I have Win7 and Lubuntu installed as dual-boot, that was quite simple. But how to remove Lubuntu?...seems, at first glance, not so simple. How to do this without leftovers?

Thanks for you advice.

  • Boot gparted live-disk or ubuntu live disk(if it was ubuntu live disk then install gparted partition editor).

  • Delete the Lubuntu partition through gparted.

  • After that ran boot-repair to repair your grub.
