After restoring from TmeMachine I have only an ER BOOT drive. What happened?

My computer was very slow. Disk Utility from repair/utilities partition reported I needed to reformat and restore from TimeMachine. After restore thermometer indicated completion hours later, the spinning beach ball persisted. After a longer wait, I stopped the process (force quit with on-off button). Next, the only boot-volume was named "ER BOOT." This crashed into the monitor then restarted in an endless cycle. I am currently giving the process a second chance. What is happening?

MacBook Pro, OS X Mountain Lion (10.8.2)

Sounds like a crashed HD. Restart in the Restore Partion and check the S.M.A.R.T. status of your internal HD. If you cannot start in the Restore Partition that has verified the disk needs to be replaced.

I had checked the SMART status earlier and it was okay. I can also start windows on the Boot Camp partition. If I replace the drive can I restore from Time Machine?
