If i wanna use more linux...and well...i am a absolutly Greenhorn....thats the reason for stupid question...what i have to lrn

Answer 1

I would start with a basic Linux distro like Ubuntu.

Checkout the Synaptic Package Manager and you'll be impressed with the amount of apps available in that particular OS, which is Debian based.

You can even install it beside windows, by changing your boot in BIOS to the USB flash drive stick you'll download it from.

It's very easy to install, and use. I'd start there, and at the command line once you have it installed.

Answer 2

use distro that support live cd/usb.
you can decide which one that easy for you.
as @Dwight suggested, ubuntu is good choice.

Answer 3
