Hide input cells #32. That would make the ability to mix hidden python stuff with purposefully displayed python. I struggled with this, too.

An ISO file is a complete copy of a CD or DVD. You can create ISO images yourself or download them from the Internet. For example, Linux distributions offer freely downloadable ISO files that you can burn to disc. You can use an ISO image in a variety of ways. The ISO file itself is a backup of a disc, so you can use the ISO file if you ever lose or damage the original disc CDs Are Not Forever: The Truth About CD/DVD Longevity, Mold & Rot .
Kyhi said: The ISO file does not belong on the DVD - the CONTENTS of the ISO are what should be on the DVD... If you have the ISO file on your HDD - double-click the ISO to Mount it as a DVD.. The point to the install.wim within the mounted ISO. Sorry - that was just bad use of English on my part. The DVD is inserted in the player and I am pointing to the contents of it, not the ISO image.
