If you’re going to dual boot, the latest version of Fedora makes that really easy to set up. Linux Mint is also a really good choice. For the love of god, avoid Ubuntu like the plague. It is not user friendly anymore. If you ever have to look up a guide on how to set up Flatpak, you’re in the wrong distro. Flatpaks should be front and center in the software center.

Btw, you don’t download installers from the internet like you do with Windows. You install software from the software app. On Gnome, it’s called Software, and on KDE, it’s called Discover. Fedora offers both Gnome and KDE. Since you’re new to Linux, I’d recommend KDE. It’s similar to the Windows layout.

Then Mint uses Cinnamon. It’s similar to a Windows layout. I don’t know what the software app is called. Cinnamon is really user friendly and familiar. You’d like it.

Since Linux is free and easy to installed, you can try out all three and see which one you like. If you’re dual booting, that might be a bad idea, so instead, try them out using VirtualBox in Windows.
