restore grub

[Linda Vest Castanos]

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

the link above shows how to restore grub after an XP install.  Will the
following commands work for error 17? If not, can I restore XP MBR
(which I have done many times) and will it work then?  

I'm not a Ubuntu-Linux guru and the commands below would work for ME,
which is from the link above.  I seem to lose my MBR approx twice a
year.  (big hassle)
thanks, Dennis

1. Boot the Desktop/Live CD. 

2. Open a terminal (Applications -> Accessories -> Terminal) 

3. Start grub as root with the following command : 

        sudo grub

 4. You will get a grub prompt (see below) which we will use to find the
root partition and install grub to the MBR (hd0,0)

                 completions of a device/filename. ]

         Type the following and press enter: 
        
        find /boot/grub/stage1
        
         Using this information, set the root device: 
        
        grub> root (hd0,1)
        
         Install Grub: 
        
        grub> setup (hd0)
        
         Exit Grub: 
        
        grub> quit
