if u dont want to waste time on setup / config / hd partitioning / choshing option
go for it :
http://www.knoppix.net/
u just need a CD to run it, it's based on Debian + KDE
It' will save your time & mind , then if u will chose to go for Permanently on linux u will be to install it on HD or maybe go for RH or wathever
good luck
