These poor smileys would prefer to celebrate Xmas.
Your problem is difficult to answer without profound information about your setup.
But reading that appsaudit decided to use /mnt/hda1/tce I guess you did an ordinary hard drive setup following the official
TC installation guide.
Maybe later you've mixed something up and happened to 'install' your aurora in a wrong place with the consequence that your system doesn't know anything of this wild 'install' and you have to repair it by hand.
Have a look into the file /opt/.filetool.lst. It the directory 'opt/tce' mentioned there?
If yes, have a look into that dir and decide if it would be OK to delete its whole content.
If yes, delete the line 'opt/tce' in your /opt/.filetool.lst file, reboot and hopefully (if no other bootcodes are working in /mnt/hda1/boot/grub/menu.lst) your arora is away.
But should your setup be different you need to give more detailed information, pastebin of /mnt/hda1/boot/grub/menu.lst and /opt/.filetool.lst could be helpful.
Good luck
