I found the below (though modified to fit my drive) in a linux forum,  I 
figured (correctly!) since Ubuntu is Debian based, it might be relevant 
to my problem & of  some help... I not only got GRUB2 back (v. 
1.98~20100101-1), but my monitor is functioning properly as well. Thanks 
for the PATIENCE on this list. Learning in the dark ain't always so neat 
& clean.

Henry
P.s., though I incorrectly called it 'pmagic', it actually is called 
'Parted Magic' http://partedmagic.com/download.html &  for any Debian 
Lenny operators out there, I'm highly recommending!

How to reinstall Grub 2 after reinstalling Windows XP/Vista/Win7
Now grub is updated to grub 2,after a long period of "no development" in 
grub code.
The issue is grub 2 is totally different from its predecessor. menu.lst 
doesnt even exist. It is replaced by grub.cfg which have little 
resemblance with menu.lst which makes things a liitle difficult.


Now with the release of Windows 7,most people must be upgrading their 
old windows.This results in loosing grub. The method to restore grub 2 
is entirely different from reinstalling old grub,so dont attempt old 
methods (even Auto Super Grub Disk software wont work)

Insert ubuntu 9.10 karmic live cd

Select "Try ubuntu without any change to current system" option

Open Accessories >terminal

Type:
sudo fdisk -l

This command will list all partions in hard disk
find the partion ,in my case it is sda3

sudo mount /dev/sda /mnt
sudo mount --bind /dev /mnt/dev
sudo chroot /mnt
update-grub
grub-install /dev/sda
grub-install --recheck /dev/sda
sudo umount /mnt/dev
sudo umount /mnt

Now reboot, you will find that grub only contain ubuntu
Dont panic!!! we are not yet done

Boot to ubuntu
Open Accessories >terminal
Type:

sudo update-grub

Now reboot
You will now have the update grub2!!!!!!!
