When you say "believe that hda1 is my /" I assume you mean that the
kernel is passed the root=/dev/hda1 option and/or the grub root device
is being incorrectly set to (hd0,1).  If there is something else, please
specify exactly what you mean.

The update-grub script gets its default options from comments in the
menu.lst file.  To change the kernel root device option, look for the
line
# kopt=root=/dev/hda1
and change it to
# kopt=root=/dev/hda2
then run update-grub and it will rebuild the automatic kernel list using
the changed kernel options.

If the problem is that the grub root device is being incorrectly set,
change
# groot=(hd0,1)
to
# groot=(hd0,0)
then run update-grub and it will rebuild the automatic kernel list using
the correct grub root device.

Also, please have a look at the update-grub(8) manual page, which
explains these options.

Cheers,
Kevin
