Download linux to a blank computer

How to download linux to a blank computer?

The site below has info and links for more Linux distributions then I've ever heard of. So pick a distribution, follow the Download Mirrors link and the download links on the following page(s) and you should find ISOs you can download and burn to CD or DVD depending on what type of disc that particular ISO is for. (If you can burn DVDs a DVD version might be easier 'cause it may require multiple CDs for a CD version.)

Note that Live CD versions are not always intended to be installed, they're intended to be booted from the CD drive.
