@ Justin: I agree that he needs to eventually get the burn to work, but for what he's trying to do now (i.e. burn the XP CD) it is not necessary in this case, since the XP .iso is already on his hard drive. Sure, he could spend a couple of more hours attempting to burn it to a CD, but I'm pretty sure if he's had this much trouble with it already, it would make far more sense right now to just copy the contents of his XP CD .iso to a directory on his hard drive, to create the UBCD4Win build from. Of course, after he does that, though, he will then need to burn the UBCD4Win .iso to a disk! :brows: But at least his situation will be that much farther along than before, which it wouldn't be otherwise.
Even if he burns the XP CD, he will still need to copy over the files on his CD to his hard drive anyway, to build the UBCD4Win build from, since they recommend it, due to problems one might have with reading a disk, etc.
