Okay - I have a computer that WILL NOT boot up. -
Win XP -Pentium 4 -256mb ram- Nvidia something graphics-.
Safe mode wouldn't even work. This computer has some pretty important school and work files on it. I asked around some different message boards, and tried a couple of things - nothing worked. Then someone mentioned Knoppix to save the files!! So I downloaded it : the file I downloaded from a mirror is called KNOPPIX-STD-0.1.ISO

I burned said file, exactly as it appears, to a disc - changed the computer to read from the cd-cdrive (which is IDE), but nothing happened. I keep getting "no operating system found, hit F1 to try again".....

What do I do now? Did I download the wrong file?

PS - I basically wanna use this ONLY to save my files - so I don't want to get TOO involved (it seems quite involved/scary).
