Only problems people have, myself included as I said in the tutorial is this, and yes, I also have installed loads of CD Images to HDD's but the way this is done with the little dos programs, it throws error messages and never seems to work. You can install the OS by actually using the HDD in your working comp and treat it like a new hard-drive,(disconnect the one in just now), then take it out after this and put it back in the dell, it will scream for drivers but normally works and you can hook to the net and update the drivers. This is another way we install OS's but again not always sucessful.
