I had the same experience long time ago: attempted to install, failed in figuring out how to mount a hard dive and gave up. Last year i tried linux mint, loved it. Easy transition, minimal learning curve.
Ive also found that if i had issues with windows the error messages were crap ans the web was filled with garbage advice. On linux, i find whenever i want to do something the support is better, advice is clearer and when you need it there is much more clarity on what is working or not working.
Grab yourself a usb stick, get your linux distribution of choice on it. Most distributions allow you to boot your machine from the stick to try out linux with zero impact on your existing machine. You can check ifndisplay, sound etc works and if you like the feel of it. If you do, install is a few clicks away using the same stick.
