i have a PC with no optical drive and i have a valid windows 7 home premium install cd. There is another PC with optical drive. The PC's are in the same LAN, so probably you can install it via network. If it's not working is have usb key, you could do bootable usb or something. I don't have time to figure it out how to do it. I have SSD in the new PC, i need the best possible performance. I think some free bootable usb key makers don't support the best disk formats. Maybe i'm wrong.
