Here is another possibility to consider:
Install virtual machine software and then create, run, modify, and destroy as many Linux distros as you want to try them out. That is what I do.
VirtualBox is free virtual machine software that lets you run Linux (or other operating systems) in a "pretend computer". You can run multiple virtual machines at the same time with enough RAM and disk space. You can also take a "snapshot", try out some software, and then revert back to the snapshot. It is very handy. You can copy virtual machines, back them up, etc.
It is a simple matter to download an .iso of a Linux installer to create a new Linux virtual machine to try out a new distro or desktop.
Virtual machines like RAM and disk space. The standard software is VirtualBox. I run VMware because that is what we all used at work a long time ago.
