It failed for me as well. Later I tried again but with another USB stick and it worked. Sadly I didn't keep the stick that didn't work for me so I'm going to share a direct link to what worked as soon as I write this is not a sure fix. But it did help on a Windows 8 laptop that failed with what sounds like the same failure messages.

You may want to reconsider your sequence. That is you tried to do this AFTER installed Norton. That could result in such failures but as you know, Norton lost me years ago.
