My computer currently dual boots Windows 10 and Ubuntu 16.10. After I partioned my hard drive and installed Ubuntu 16.10, I found out that I had gotten the 32 bit version. I want to be able to revert back to Ubuntu 16.04 (which I already have a bootable for), and delete Ubuntu 16.10 off of my hard drive. What are the steps that I need to follow to accomplish this? I am a little bit of a novice when it comes to this kind of thing, so a step-by-step guide would be greatly appreciated!!!
EDIT: When I say "revert", I mean how do I go about reinstalling. How do I delete the Ubuntu 16.10 partition, and install 16.04/17.10 in its place? Also I am dual booting with grub, and from what I have researched, deleting Ubuntu could mess with my ability to access my windows partition. Sorry for the lack of Clarity.
