grub not configured properly after 8.10 install

[Graham Watkins]

Hi folks,

Finally plucked up the courage to install 8.10 but didn't want to 
install over my existing 8.04 installation. I have 2 hard drives: hd0 
which formerly contained a now unwanted Mandriva system, and hd1 where 
my 8.04 installation resides. I therefore installed 8.10 on hd0.

Although the installation went through without incident and announced 
that it was searching for other operating systems, when I rebooted the 
grub menu showed 8.10 only.

With the aid of a supergrub disk (with which I cannot claim any great 
expertise) I have managed to boot 8.04 again although not to build a new 
grub menu containing both OSs.

For the time being I want 8.04 to be my main system as I have it 
configured the way I like it - which took some time. 8.10 for now is 
just to play with.

Is there a quick and dirty (ideally GUI based) way of re-writing grub 
which will permit me to choose between the 2 systems without continually 
having to use a boot disk?

I have tried using the 8.04 install disk to rewrite grub but ended up 
just installing 8.04 over 8.10.

Ideas anyone?
