@Israel:

Thanks for that data, bit of a scramble this morning, but I'll check into
it when I can find a few minutes . . . .  Still wondering why I would need
the install CD or "chroot" (still don't know what that is) . . . when I can
still boot into the 14.04 system . . . after using SG2 to boot it up.  Then
I can use the Terminal and all that stuff . . . it just won't show up when
using the option key . . . or in rEFInd . . . .  Back to you later when
I've tried some of this stuff out.  I read through the links you provided
yesterday, and some of that, about using the "GRUB command line" might also
help out . . . .  Or, nuke and pave???? remains to be seen.
