Further to the questions I raised, I downloaded supergrub2 and I was able
to access the system.However, after starting 3.9.3.slh-1 and running
update-grub and grub-install /dev/sda0 ( the installation finished. No
error reported) still, on rebooting, come to the same error of file not
found and getting into grub rescue mode. I downloaded bootinfoscript and
ran it to get the bootinfo which I give below.There is
only one peculiarity . It says v.1.99 is installed but my grub2 id 2.00-14.
Though I ran grub-install again which said Installation finished. no error
reported , I ran bootinfoscript again and the version of grub is 1.99.
Though I came to operating system through supergrub
as far as I can see the system is under the control of my operating system.
Can somebody clarify how version 1.99 of grub is installed when the grub2
on my system is 2.00-14. Will I have to blank out my MBR and start all over
again.

Results of bootinfoscript:
Grub2 (v1.99) is installed in the MBR of /dev/sda and looks at sector 1 of
the same hard drive for core.img. core.img is at this location and
looks
in partition 98 for .
=> Grub2 (v1.99) is installed in the MBR of /dev/sdb and looks at sector 1
of
the same hard drive for core.img. core.img is at this location and
looks
for (,msdos1)/boot/grub on this drive.
