Installing Win7 From a USB Drive
Friend and all around nice guy Steve Smith wrote
this blog entry
about how to install Windows 7 from a USB key. Quite a few
steps, but I've done this before so I know it works. I began
thinking what the Apple story would look like and smiled: 1.
Download OS X and save it to your USB drive. 2. Reboot. :)
Seriously, though, I had to track down lots of steps when I
did it a few months ago so Steve's entry will be helpful to
many.
