okay, for those that want to learn what the problem was keep reading:
Problem: computer didnt see the cd-rom drive I had, thus no operating system could be installed through any CD (which is the most common way to install OS's) easily for a newbie that is.
Solution: make a startup installation disk. Why? The computer doesnt recognize cd-rom drives, because...well...some just dont at the beginning when you have nothing installed (including any old operating systems). The key item in the startup installation disk is the top secret, one could say lol, cd-rom [drivers] for the most common CD-ROM drives. The cd-rom [drivers] are files that make CD-ROM drives do what they do (or should be doing). If you dont have the driver, the drives won't work. When the drives dont work, you cant use the CD-ROM installation method. Wow, I WAS stupid, but now I know..
