Grub, pata, and sata
 
I've just filed bug 0004634. Grub won't install onto my pata drive now
that I have a sata drive installed. This is grub 0.97 on CentOS5.5.
Has anyone else encountered this? I'm guessing that I can always
install Fedora on hda, which should give me a working grub, but I was
hoping for something a little less involved.

Thanks,
Dave Mackay

Is the PATA drive on your Primary Master connection?

If you use Gparted live CD or Parted Magic, how do those
drives show up?

every time i reported this bug on some previous fedora versions, it was closed with notabug:"As mentioned in other bug reports, this isn't really a bug. There's no way for

the drive order to be consistently detected."

It's not a matter of drive order. Grub simply will not install on hda.

Even if the order were wrong it should still let me install. If it was
installing on the wrong drive, that would be a separate issue.

maybe something like this?

cat <<EOF| grub --batch --no-floppy
device (hd0) /dev/hda # setup hda for 1st disk
root (hd0,0) # /dev/hda1 for /boot
setup (hd0) # install on MBR of /dev/hda
