is that something todo with ur hdd(bad sectors)?
otherwise chroot /mnt/sysimage might had worked.
another option is setup grub manually.read 'man grub' for details
#grub
grub>root (hd0,0)--->(if hda1 is your root)
If you are not sure which partition actually holds this directory,
use the command `find' (*note find:
, like this:
grub> find /boot/grub/stage1
Once you've set the root device correctly, run the command `setup'
grub> setup (hd0).this may solve ur problem.u can either install GRUB in
MBR or First sector of /boot partition.B'O'L
