I kept receiving an error on my Dell laptop during the Expanding Files process of the install. It kept stopping at different percentages indicating it couldn't find a file believing it was corrupt. I tried this serveral times from the USB install, finally burned an ISO and tried the install that way. Both failed. In a last ditch effort, I unplugged the laptop and let it run on battery power. I have no idea why but after 5+ failed attempts to install fresh, it got through everything (using my USB driver) the first time. After the install was complete, I plugged it back in and everything is working as it is expected. I just hope this helps someone else that may be (or will have) the same issue.
