Which Linux distribution is best for a beginner on this Lenovo laptop?

You could also consider MX Linux with XFCE or KDE if you want something a bit lighter, but your laptop is powerful enough that this isn’t necessary. Pick a mainstream distribution, use it for a few weeks, and focus on learning the tasks you actually need rather than trying to understand every part of Linux at once.

My recommendation would be Mint Cinnamon. It’s a comfortable starting point and doesn’t require much technical knowledge. Avoid Arch, Gentoo, and other highly hands-on distributions until you understand the basics, unless you specifically want the installation process itself to be a learning project.

That hardware is more than capable of running practically any mainstream Linux distribution, so you don’t need to limit yourself to an ultra-lightweight option. Linux Mint Cinnamon is probably the easiest transition from Windows: it’s stable, familiar, and well supported. Zorin OS is another good choice if you want an especially Windows-like interface.

Before installing, make a bootable USB drive and try the distribution in live mode. This lets you check the Wi-Fi, sound, graphics, touchpad, and other hardware without changing the internal drive. Once you find one you like, install it. You can always try a different distribution later if the desktop or workflow doesn’t suit you.

Ubuntu, Mint, Fedora, and similar established distributions should all work well. Mint generally prioritizes stability and a familiar desktop, Ubuntu tends to have excellent out-of-the-box hardware support, and Fedora offers newer software and kernel updates. For a Windows-like experience, Cinnamon or KDE Plasma are good desktop choices.
