Windows 8 cd w/dead cd drive

Hey, have a strange predicament. I have a legit physical copy of windows 8 and just discovered I have no working optical drive within reach.. :(

I suppose I could torrent an iso and stuff it on usb, then just drop in my key. I was just wondering if anyone knows of a more legit/official place to do get my grubby hands on it?

if you can use someones computer that has a disc drive just use there computer and make a bootable usb with the windows 8 on it to install

I would but I am kinda stuck here for a few days with this and my old netbook, neither with a working optical :(

Edit: It's late and I'm dumb.

This might help.
