Have a look in the grub directory listed above
/mnt/hda1/boot/grub
it should have the same files there
as in /mnt/hda1/usr/share/grub/i386-redhat
I would not expect them to go missing though.
Maybe grub has gone missing from the MBR of /dev/hda
If you are up in Morphix then it should be possible to
install grub from there.
BE VERY CAREFUL Though!!!!!!!
Make sure you run the FC3 version of grub
/mnt/hda1/sbin/grub
try things like
grub>cat (hdTAB The TAB char tries to auto complete
so that you can clearly identify which drive is which from grubs point
of view.
grub>cat (hd1,0)/boot/grub/grub.conf will hopefully list the
grub.conf on the disk in question.
When 100% certain which disk grub and you are interested in
then?
grub>root (hdx,y) tells grub which disk the files are on
the stage1, stage2,.. type files that is
grub>setup (hdx) Writes to the MBR of hdx
x and y MUST be correct or disaster is likely !!!!!
An alternative is to boot the FC3 CD1 and enter
linux rescue which will give you a shell prompt
where you can issue the same commands
