Bit of a vague post, but I suggest Trying any distro honestly. You can load it on a USB and use it directly off the USB, no commitments. I bit more of a commitment, dual boot a Linux OS. Very easy and allows access to Linux and windows.
I use Ubuntu and enjoy It a lot.mint is another good one I used to use.
I would also suggest figuring out what apps you need to see if they work on Linux, or if there are workable alternatives.
Sounds good!
