    Interesting. What kind of computer do you have? Has it booted from a CD before?

    I followed the directions, but when I start the computer (booting from the CD), I get the error, “CDBOOT: Couldn’t the NTLDR”.

    Hmm, Murph, I’ve never heard of an error 4. What is generating this, your boot bios. What exactly happens. Have you tried this on other machines.
    George, what this means is that there should be a magic file called boot.bin, it is a tiny file that your PC picks up when the CD is inserted, it is the thing that makes the CD bootable, so with the version of Nero discusse, when you did a bunch of copying, one file that should be there is boot.bin.
    When you are in Nero, you find it and then select this as the file to boot from.
