That's odd, usually time machine drives are themselves bootable, to allow you to reinstall the os prior to restoring the backup on them.
Am I missing something? AFIK, TM backups are not bootable. You can restore from them via the Recovery Partition or by entering TM while booted from your main drive (partition) but otherwise, that's it.
Well I was referring to the time machine
drive of course, which typically has a recovery partition ON it. So if your hard drive dies completely and has to be physically replaced, you can just boot off the recovery partition on your TM drive, restore your os to your computer, boot off THAT, and restore the TM backup.
