I would try using this

    find /etc/ -type f -exec grep -H 'boot sector' {} \;

to find the startup file that is producing the error msg and
see what's going on there.

IIRC, that simply skips the "fsck" file system check for the hda1
partition.  Probably, it skips a whole chunk of script where some
backup MBR is also checked.  (I've never heard of such a check -- it
might be something new. I'll guess you should make a backup of the
backup before backing up the MBR again, since if you keep them the
same, there's no reason to have two, if you know what I mean.)
