Did you know that you can run a complete Windows 8 operating system on a USB? Yes you can, with Windows 8 Enterprise.
What you basically need is a USB drive (USB hard drives are much faster and is highly recommended), and a Windows 8 Enterprise iso image, it doesn’t matter if you have 32 or 64-bit version, although if you’re going to use it on a processor which only supports 32-bit, then you need a 32-bit version, otherwise, you can go for 64-bit version.
Check out this article to learn how to achieve this.
For formatting your USB, I highly recommended RMPrep USB tool, accessible also from the link above, just click on the download link on the top to download the tool.
Note: This will probably not work on a Mac with Bootcamp, since Macintoshes used EFI motherboards rather than BIOS, so do not try this – it won’t work!
