A laptop is encrypted, the OS crashed, in system repair the fixmbr and fixboot command was ran.
The preboot authentication doesn't load.
The decryption has been tried with a recovery media but no volume was found.
DMU tool fails to decrypt with the message "Can't find system area, try using recovery file instead"
Loading the recovery file in DMU gives the authentication window for the selected drive but after authenticating nothing happens. The drive isn't accessible.
What else can be done to recover the data from the drive?
