Is this a typo? sda0 ? If you want grub to go into the MBR of your first
disk, than you need to specify
/dev/sda (i.e. the device, not a partition). There are many howtos out
there, for instance this here:

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:

in partition 98 for .

Hi : I have a hard disk /dev/sda and a removable disk /dev/sdb The

/dev/sda2 has a linux

Yesterday I was upgrading to Linux 3.9.2 and thereafter I got
this error. The updrade did nt\ot go to
completion. I have a super frub rescue disk with which I can start
3.9.2, but I am unable to repair the grub with update grub and
grub-install /dev/sda. I have blanked out the first 512 sectors of
dev/sda but that didn't help. Presumably grub is unabke
to find grub.cfg.Trying to run grub-install with other versions of
Linux did not help. /s /this a bug in grub or is there something
I can do to overcome this. I cab see in
Google thaqt others have had this file not found error. I have
tried every likely thing ,but I am aksways left in rescue mode
when booting, I'd appreciate any suggestion
Are there any logd which I can look at?
