Two systems, want to migrate to ubuntu

Question

On my laptop, I had two systems - Windows 10 and Ubuntu 20.04. After using Ubuntu for several days I decided to fully migrate to Ubuntu.

How can I do this without losing any data? (in Ubuntu)

I understand that I need to somehow delete windows partition and extend ubuntu partition. I am worried that I can lose some data on the way...

Can someone explain to me step by step what should I do?

The only way not to lose data is to backup. So, backup all important data first, then proceed. — mikewhatever, Jul 18, 2020 at 22:38

In addition to any partitions related to Ubuntu, you will also need to keep your EFI system partition.

You can remove the other partitions that are exclusively used by Windows.

Back up first, in case you make a mistake and remove the wrong one!
