Other means of installing windows 7?

I’m currently running Windows 7 on the computer I’m currently running, but I would like to install it on my old computer as well. The old computer doesn’t support DVD disks, yet does support CD disks. The Windows 7 ISO is too large (3.47 GB) of a file to fit on a CD. USBs don’t work either.

Is there any other means of installing Windows 7 on my other computer, such as an Ethernet cable or whatnot? Or even have the OS install when the computer restarts with some program?
