How to start with LinuxDownload a ISO image of Linux Mint to your desktop, then use a CD burning software (I use Roxio) to burn the ISO image onto a bootable CD that you stick in your primary optical drive and then you boot off of it.
Me, I always stick with the Mint LTS versions as they were cherry picked for stability and they are supported for 3-5 years now until you go to the next LTS version for the next 3-5 years.
I find that I actually like stability and boring ....
Next, once you decide to install the software after you play with it a bit, only install it as a dual boot system (keep your old windows and all your old stuff) because nobody really goes over to Linux cold turkey all at once. You can tell your boot loader which OS to boot first, it doesn't really matter much which you want to use mostly. You can autoboot to Windows, it won't hurt my feelings.
What will happen is what always happens ....
Windows gets all forkled up with a trojan attack, or a virus, or a bot, or (heck you name it -- something new most likely) and you wind up using your Linux in the interim while the Windows anti-virus packages catch up with the new nasty. And you go back to windows as soon as it is cleaned up and working again.
This happens 2-3 times until you get hit with a good one and your Windows won't fix without a total hard drive scrape job (system recovery from the boot prompt).
???!!

..... and you suddenly realize you don't want to fork up your Linux by doing that because most of your working stuff is over there now.
Your Linux Mint kept right on working right on through the worst the nasty attack boys could throw at you and it didn't even bobble once. Your Linux Firefox has all your stuff on it and you got used to Open Office now to the point it doesn't really matter which one you use.
You find yourself liking the rapid boot times, fast response times, and the fact that the various Linux softwares can read corrupted windows files that windows can't even SEE the durn things any more, and fix them.
Why fork up something that works good for something that doesn't?
Now you have become an "at heart" Linux user .... heck, next time you may just let Linux take over the whole c: drive and simply quit trying to fix Windows each time it gets crapped up.
Retired people can make this swing over easier than working folks can, although Open Office can read it and save it all, there are some softwares (graphics and games) you use that only exist in Windows.
This may change with Win 8 as Win 8 will force a major software upgrade for all active softwares to be compatible with ARM chipsets. Once this is done, the stuff may wind up being a lot more Linux compatible as well .... (but not if Bill Gates can help it -- he has to keep you feeding his upgrade gravy train
