Hey there, I realize I am replying to a rather old thread, but wanted to do so in the event someone needs assistance in the future 
Some older macs do not boot from USB, for example my mbp cicra 2004. It makes installing a head scratcher for sure, especially if you don't have a working dvd drive.
One possible solution is Apple's Target Disk Mode. Target Disk Mode allows you to mount your mac's drive on another mac. To use it, you'll need another mac that can boot either from a USB or DVD. This will allow you to run the installer on the secondary machine, but install on the target machine.
Convoluted as heck, I know. But from experience it works. Check out this article for more info on Target Disk Mode:
