IntroYou can boot off a flash drive with Linux, it’s super-handy but might not be your cup of geek, so here’s a way to do the same with Windows – “All it takes is a minor error in the Windows Registry or a virus infection, and your operating system can become unbootable. But with a properly configured USB flash drive on hand, you’ll always have a compatible replacement no further away than your pocket or keychain. In addition, the flash drive can also provide a secure browser and virus scanner, and lets you take your favorite DVD burning and Office software with you wherever you may go.” Link.
