I solved it. I have needed disable FileVault before try to install 10.8.


In other words:


  1. I used the disk utility to format my partition without cypher, aka without FileVault.
  2. Restore 10.7 from the time machine backup in this partition.
  3. After that, I upgrade to 10.8.2. without any problems during the installation.
  4. In the end, I enabled FileVault.


See you...
