I was trying to avoid wasting peoples time with a long description.

When I first boot I get the Fedora grub splash screen/menu twice --
besides that everything else boots normally.

About four weeks ago my commercial boot loader was blown away by the
WindowsXP sp3 download and install.  Fine and good: that didn't surprise
me.

I just installed grub.  During a first attempt at a grub install I had
an ooops! So I just re-installed grub and everything seemed fine.
Because it was an oops and not a confusion, I didn't pay attention to
the mistake, so now a month later I have forgotten exactly what I did
wrong.  Besides I thought I had recovered.

About a week ago (I don't re-boot very often), I noticed the Fedora
grub splash screen appear for 1/2 second or less, then go blank and
pause for a second or two.  Then a new splash screen appeared and
everything progressed fine from there.  This occurs definitely during
the grub stage of bootup. 

I didn't do anything then because I was going to fresh install Fedora 9
with a new grub on the weekend.  Which I have done.  But the double
splash screen still appears.

I will use the grub command as you have given me to see if I can find
where the problem is.

The problem is, I think I have two stage2s.
