Hi ericat,
Absolutely it'd be possible. I suggest you start with a Live CD of a simple, newbie-friendly distribution (maybe
Ubuntu,
Linux Mint or
PC Linux). Burn the CD as an iso, define the boot priorities in BIOS to start looking for the OS from the CD drive rather than the hard disk, and you're away. Note, and this is a brand new development, you can now install Ubuntu Linux with
Wubi. Download Wubi onto your Windows desktop, double click the icon in the traditional way and follow the instructions! It's the exact same procedure as installing anything else in Windows. Wubi will give you a good idea of what Linux is like, but the performance it probably not as good as a "genuine" install. This is because Linux needs a certain type of format - but the advantage of Wubi is that it gives you a very safe way to try, and if you decide you don't want to continue your Linux experience, you can very easily uninstall it.
