Windows was unable to locate the required installation file [boot.wim]. Verify that the installation source is valid, and restart the installation.

That file is in the Sources folder. If you used MagicISO to burn the DVD, you might have a problem something like that. I had to use UltraISO to burn a bootable and installlable DVD.
If you don't show the file in the sources folder, your download might be bad.
You do not have a boot.wim file in the sources folder. That is impossible as far as I know!
You should show a background_cli.bmp then the boot.wim file.
