My computer is running Windows XP. When I restarted it, I get a message that says "BOOT DISK FAILURE, INSERT SYSTEM DISK AND PRESS ENTER". This sounds like a pretty easy task, except that I don't have a system disk. I must have forgot to make a rescue disk in my haste. When I bought the computer, I was told with the new feature of restoring the computer from an earlier save, that the new computers didn't have a system disk with it. What can I do without having to go out and buy a new XP operating system disk at the store. Thanks.
