I needed to restore my Toshiba M400 Tablet to it’s factory build at work today, but I’d forgotten to bring in my Restore DVDs. Fortunately, I found a short-cut that allows you to restore the system directly from the hard drive.
Hold down ‘0’ (zero) during boot and you’ll go into the Toshiba recovery console. About 30 minutes later I was running through the Windows XP initial boot questions.
