I ended up commenting out (#) those last two entries. Of course tested
with 'sudo update-grub' and they came back (expected). Commented them
out again & life in the boot lane is much easier now. I'll wait to see
if the new kernal updates that seem to be appearing every few days (I'm
on -20 now) will change the commented out grub.cfg entries. I suspect it
The problem with the /etc/grub.d/40_custom (as far as I can tell) is
that the file is intended to _add_ entries, but not remove entries. So I
may still try your last suggestion.
Also, wrt my comments about grub2 being a PITA; I am referring to issue
like this whereby there are so many interacting files that it is
difficult to simply edit one file (as in 'menu.lst') and have the
preferences stick. I'm quite happy that grub2 picks up the 'Vista'
entries etc., but not happy that there doesn't (yet) seem to be a way to
refer to a 'master' grub2 menu file (outside of the generated grub.cfg)
that will allow commenting out those entries to stick.
