Not to seem ungrateful, but grubspeak is not too helpful at the moment, 
but nonetheless, I did try several of your suggestions (perhaps not 
correctly, because of maybe not understanding too well?)"

# grub-install
install_device not specified.
Usage: grub-install [OPTION] install_device
Install GRUB on your drive.

  -h, --help              print this message and exit
  -v, --version           print the version information and exit
  --modules=MODULES       pre-load specified modules MODULES
  --root-directory=DIR    install GRUB images under the directory DIR
                          instead of the root directory
  --grub-setup=FILE       use FILE as grub-setup
  --grub-mkimage=FILE     use FILE as grub-mkimage
  --grub-mkdevicemap=FILE use FILE as grub-mkdevicemap
  --grub-probe=FILE       use FILE as grub-probe
  --no-floppy             do not probe any floppy drive
  --recheck               probe a device map even if it already exists
  --force                 install even if problems are detected
  --disk-module=MODULE    disk module to use

INSTALL_DEVICE can be a GRUB device name or a system device filename.

grub-install copies GRUB images into the DIR/boot directory specified by
--root-directory, and uses grub-setup to install grub into the boot
sector.

Report bugs to <bug-grub@gnu.org>.

This was the message I got... I have no clue as to what "grub-install 
[OPTION] install_device" means... this is to say, what is the option?

Then I did check the /etc/default/grub file, & this is what I got (I 
took out the '# at the GRUB_GFXMODE=1440x900' & changed the 
resolution... I tried doing an '#update-grub' both in the terminal while 
booted & at startup in the recovery mode. Nothing seems to change... 
maybe it's the 'install_device not specified.' problem??
