Sorry but there are No other operating systems which have native support for EFS

Files encrypted with EFS can only be decrypted by using the RSA private key(s) matching the previously-used public key(s). The stored copy of the user’s private key is ultimately protected by the user’s login password. Thus Accessing encrypted files from outside Windows with other operating systems is not possible.
