OSX - Can't login after TM restore - 'Update Needed'

After replacing my stock hard drive with a new Samsung 830 and restoring backups from Time Machine, I could no longer log into the laptop.  After the system was rebooted, the only thing on the login screen was image that says "Update Needed":

Update Needed

You could not click on the login box, there was nothing that could be done to login.

The problem had to do with the type of partition I created before restoring the backup:

Mac OS Extended (Journaled, Encrypted)
You can not recover the Time Machine image on an encrypted partition.

After the drive was repartition with out encryption, time machine was used to restore the drive.   Everything worked as expected.

Side Note:

According to Blackmagic Disk Speed Test the speed from the stock drive was around 70 MB/s.   After installing the SSD the speed is quite a bit better:
