Hi there! I have been doing a Windows/Linux dual boot for the last 4 years now, and haven't regretted it. I like what other people say, which is try a live USB image of Linux, give Linux Mint or Ubuntu MATE 16.04 a try. If you think you can get comfortable with the UI, I encourage installing Linux to that extra drive of yours. As photonboy said, make sure Secure Boot is disabled when installing.
I like to use Linux primarily because it manages my memory and CPU time better, doesn't have a corporation breathing down my neck with every click I make, and it's really nice to install your OS and be up to date in less than an hour and have probably 90% of the applications you will want to use already installed. I have had many people I know using Linux and I typically hear from them that they find using Linux more straightforward to use. Just remember it is a DIFFERENT operating system.
Finally, if you are wanting to dual boot, remember these things:
* Make sure Windows is installed first, THEN Linux (so the bootloader Linux uses is what it used)
* Do manual partitioning when you install Linux to your drive, so you can choose to use your extra drive
* Look at guides on how to partition your disk
* Put the bootloader on the same disk that you install Linux on
IMO, the installer Ubuntu uses (which also means Linux Mint and Ubuntu MATE) is the easiest OS installer I have used to date.
I think Linux is worth using and learning so you can see if you do in fact enjoy having an alternative OS (or an OS to do another job), and Linux is also great for things like web servers, application servers, media servers, file servers, you name it. Linux has allowed me to do things that I can't do on Windows and for free!
