Restore Database clarifications
Since database server was rebooted while restore process was still going on so the restore process did not completed successfully.Restoring database with recovery is not going to work it will flash an error. What you have to do is


Open new query window, connect to master database and drop the database which is in restoring state by drop database db_name;
Now start the restore process again.


You should have waited to restart the machine after it prompted for reboot. I am sure it would have prompted but you would have selected for reboot then only it went ahead and rebooted. Avoid rebooting SQL servers when restore process is going on this would disrupt restore process and you would have to start all over again, which is waste of time.
