I just bought a macbook air and i'm thinking about installing windows on it via bootcamp. The only problem is that it doesn't have an optical drive. I didn't buy the superdrive because I will never use it.

I have a usb-usb data transfer cable I can use between two computers, so would it be possible to put the windows disc into a PC, run the usb-usb cable to the air, and then use the disc that way?

The other idea I had was buying a cable like this to directly connect my dell optical drive to the air via usb.

Anyone have any idea if either of these will work? I'd rather not buy an optical drive for a one time use.
Thanks!
