I installed Ubuntu some time ago, and it went bad. I then uninstalled it, and a few weeks later reinstalled it and it went fine. Later I uninstalled it also because of some problems, and after all of that I saw that I had still two Ubuntu boot options on my UEFI manager (image below). Windows booting is functioning well.
Now I want to install the newest version of Ubuntu, but first I want to correct all things. So, what I would like to know is if it's ok to just select the Delete boot option for both of them.
