I am trying to reinstall the boot loader.

[Stephen]

I'm sorry if I hijacked some one's thread, I don't know how I did it but 
I will take your word for it.

I have two drives hd0 is a windows drive, and hd1 is ubuntu.

As the web page  at

https://help.ubuntu.com/community/RecoveringUbuntuAfterInstallingWindows

said;

I booted from a live cd.
mounted the Ubuntu drive.

Typed mount | tail -1
then ls /media/drive-designation/boot

I got a listing similar to the shown listing on the web page.

I typed sudo grub-install --root-directory=/media/drive-designation/dev/sdb

sdb was what the web page told me to use.

When that didn't work for all the items in the list to work I used
/dev/sda

That had exactly the same results.

When I took the suggestion to use sudo grub-install /dev/sda from my now 
working in stall of Ubuntu, and rebooted it gave me the prompt grub> I 
didn't know what to type so I used the live cd again.

So I had to use the live cd and reinstall the boot loader that way, and 
Ubuntu is still the only operating system that will boot.


I will be grateful for any help I can get;
