installation?
 

I have no blank cds but i would like to install linux on a secondary hardrive. Can that be done?

it can. google for: linux alternate installation methods

If yours is a big distro (big as in popularity, not size), look on thier site and thier docs.

as said above. You can create a boot floppy and install via nfs, ftp, http, fm another hard drive, via serial cable, and soon to come... from magical beenstalk seeds
