What should I use?

[JustinLitteral]

I have never used Linux before, but I've always wanted to learn.  I  want to 
use Debian Linux, but I don't know which to use.  I am wanting to  dual boot 
it in my laptop with my Windows.  My laptop is made by eMachines  and uses a 
AMD Sempron 3200+ processor.  Please let me know what  version to install.  
Thank you very much!!!
