I am trying to install 64 bit Windows 8 on my Mac Machine (Mountain Lion OSX) using a USB as a boot drive. For some reason bootcamp requires atlesst a 8GB USB. I however only have a 4GB USB. Is there any way I can override the 8GB minimum considering the size of the ISO is only 3.3 GB?

You could choose not to use Bootcamp I suppose. My suggestion just go out and buy the $9.99 8GB drive. –  Ramhound Sep 17 '12 at 16:25
@Ramhound It's not the price I have a problem with. It's the inconvenience. –  user117094 Sep 17 '12 at 16:34
Will Mac and Windows be on the USB drive, or just Windows? –  mcandre Nov 4 '12 at 4:38

Assuming only Windows will be on the USB drive, simply use the Windows 8 installer to install Windows 8 on the USB drive.

When the computer reboots, hold the Option key to choose whether to boot Mac or Windows.
