JBC,
Does Linux include a reformatting program
Yes as part of the installer, this is inclusive of ALL Linux Distros
where to go for Linux software
there are a few sites you can go to to D/L Linux software a good place to start is the Linux Distro Chooser, this will give you a series of questions then based on the answers it gives you your ideal Linux distro
http://www.zegeniestudios.net/ldc/
then goto a website Like
http://distrowatch.com/ to D/L the Distros or the Distro Homepage depending on which one you decide on
Can I D/L the ISO files safley
Sure you can! all you need is to D/L the iso to the HDD go to your burning application (I use nero) select the desination where you saved the file to, retreive the file and select Burn image to disk
Here are a few Personal Reccomendations for Linux Distros:
Kubuntu
http://www.kubuntu.org/
Mandriva
http://frontal2.mandriva.com/en/downloads/mirrors
Mephis
http://www.mepis.org/
PCLinuxOS
http://www.pclinuxonline.com/pclos/html/download.html
This is the distro I use and recommend, Why because it works right out of the box. No need to configure Everything, everything just works. It also comes as a 1 CD install that is a live CD that you can install later if you wish.
hope this Helps,
Jake
