Okay, will send you direct to you a grub2 iso. Burn image, not data to 
get that cd.
Just to recap, requote below earlier message (to other people) sent 
about a day earlier.

Do a search....
grub>search -f /vmlinuz

note output as in "(hd0,5)"

then do this....
grub>linux (hd0,5)/vmlinuz root=/dev/sda5
grub>initrd (hd,5)/initrd.img

note replace (hd0,5) and sda5 with the output from the search.
note vmlinuz not vmlinux; linux not linuz

After booting up,at terminal, remember to
sudo apt-get update
sudo apt-get upgrade
sudo install-grub /dev/sda

if you have error message at sudo install grub /dev/sda,
do a
sudo apt-get install grub2
sudo update-grub

note : follow instructions that follows and set to sda at "sudo apt-get 
install grub2"

good luck - goh lip
