Yes, I've messed up with Ubuntu Desktop 20.04 LTS and need to reinstall. I have my several partitions: Windows, Ubuntu, the '/home' for my Ubuntu personal data, and 'swap'.
(1) I am unsure if I need to DELETE my previous Ubuntu root partition and CREATE a new root partition using the same memory. I was confused because I saw also the option of "change" in addition of "delete".
(2) Will it recognize my previous /home and swap partitions?
Thank you in advance, and happy new year.
Well, for future generations to come I'll answer my own question:
If we have root('/') and '/home' partitions, and we delete the Ubuntu root partition and reinstall it again, Ubuntu will still use our existing /home partition to place all personal files. In short, you will not lose your personal files.
It is also no longer necessary to have a separate swap partition. When you reinstall, do not specify anything for swap and the installation will create a swapfile to be used instead.
