yes indeedy, mandrake 8.2 is what i use and i would recommend it.
i recommend you dual boot between mandrake and windows, meaning you have one system on one partition, and the other on a seperate partition. you can use a simple tool such as LiLo to give you the choice of which to boot into every time you switch on.
i strongly suggest you read a bit about what you are getting into before you do it. it will all be a bit unfamiliar to someone who has been using windows. i can remember well what i was like last year! very puzzled, but it makes sense once you actually get in up to your elbows in it!
The Mandrake User site is a really good one stop shop for finding out how to dual boot, how to use LiLo, how to install and so on. Go to their site and click "DocSection" to read their many helpful articles, and also go to their downloads section, where you can download the entire DocSection for home reading, and also download several useful utilities and programs specifically compiled for mandrake 8.2.
If you have any questions about getting started with linux, we will be happy to help you here, or i would also recommend
the New To Linux site, where they have some articles and a very friendly help forum.
good luck and i hope you enjoy your new OS, and welcome to the board!
Good luck
