You probably need to boot either the installer disk or the rescue disk
in rescue mode (this assumes that /boot is on /dev/sda1 per your earlier
message - adjust as necessary) 

'linux rescue'

follow the prompts, networking is likely unnecessary.

'chroot /mnt/sysimage'
# confirm here that /boot is where you think it is
'mount'
# if it is /dev/sda1...
'grub-install /dev/sda1'
#otherwise, adjust as needed
