[CentOS] System will not boot - faulty fstab?

I believe that I made a boo boo recently when recovering some unused
disk space.  Without going into painfully embarrassing detail I need
to delete an entry in fstab for a now non-existent logical volume.

The system reports that the there is a bad superblock for said logical
volume.  Mainly I expect because there isn't one anymore. How do I
edit fstab so as to remove the mount request?  For some reason the
system will not boot from the cdrom and the I for interactive option
is just blown by when the HDD boot starts.
