Just to follow up on the previous post.

I have a black screen with a single blinking cursor after running:
    #grub-install /dev/sda1
Never install grub's boot sector to a partition, install it to the mbr
instead (/dev/sda).

I tried to do that just now, and it did not work. I am looking for additional solutions to make my system boot and undo what #grub-install /dev/sda1 did

I tried using the CentOS 6 media in rescue mode to do this and got this error
#grub-install /dev/sda

/sbin/grub: Not found.

=> so that is not possible with the CentOS 6 boot cd in rescue mode.

I then cut a knoppix CD and did the same thing and got

grub-probe: error: cannot finda  device for / (is /dev mounted?).
grub-probe: error: cannot find a device for /boot/ (is /dev mounted?).
Could not find device for /boot: Not found or not a block device.

so my system will not still not boot after completing the advice given.

any further ideas?
