Recently, we’ve shared the fix for the issue where you can’t launch Windows 10 setup. The fix was intended to work, if you’re installing Windows 10 via Media Creation Tool/Windows Update. If you’re making clean install using the bootable USB media and you can’t fire up setup wizard, this post will address such an issue.
Basically when you’re unable to launch setup wizard for clean install, you’ll notice this error message:
