Deny permissions have priority over Allow permissions. "Everyone" well of course, affects every account and setting a Deny permission on it, does so for everyone regardless of Allow permissions the current user has. Even the SYSTEM account would be denied. You do not become SYSTEM nor do you need to.
Instead of copying everything over, be selective about it. Only copy over things that make sense to keep. For example there is no point in copying Program Files, ProgramData, Windows, etc. In perfect situations all the files you should could about should be in Users.
