The "deny" permission in NTFS is a very specialised instruction and it has priority over all other permissions levels, ji is designrd for use in Client server systems where you would normally have a Domain admin that can reset any accidents. It should be used only for very special purposes, normally only for testing, and never to whole areas.
This being said you may be able to recover data on the now locked system partition by the use of a repair install - check tutorials section for detailed instructions, though these permissions may even be to much for this, it is worth a try
